Critical Arista VeloCloud Orchestrator flaw exploited in attacks

Arista patched a critical vulnerability in on-premises VeloCloud Orchestrator, the console that configures and manages VeloCloud SD-WAN deployments, that is already being exploited. Tracked as CVE-2026-16812 and scored 10.0, it is an unauthenticated operating-system command injection that lets a remote attacker reach privileged functionality meant only for internal use. Arista warns successful exploitation can compromise the confidentiality, integrity, and availability of the orchestrator and everything it manages. There is no configuration that prevents exposure, since the web interface is reachable by default. CISA added it to its exploited-vulnerabilities catalog. Hosted and Dedicated deployments were fixed before the advisory and are not affected.

Check
Identify on-premises VeloCloud Orchestrator instances, upgrade to the fixed 5.2.3.14, 6.1.3.4, 6.4.2.4, or 7.x releases immediately, and restrict the web interface to trusted administrative networks.
Affected
Organizations running on-premises VeloCloud Orchestrator (CVE-2026-16812); the web interface is exposed by default, needs no credentials, and active exploitation gives attackers command execution over the orchestrator and managed devices.
Fix
Upgrade to the fixed VCO versions, limit web interface access to trusted networks, and review VCO web access logs for unusual path components, encoded characters, or high request rates.

Check Point patches exploited SmartConsole flaw giving attackers full admin access

Check Point has fixed an actively exploited flaw in SmartConsole, the graphical admin panel used to manage its security products. CVE-2026-16232, rated 9.3, is an authentication bypass letting an unauthenticated remote attacker obtain a login token and authenticate with administrator privileges, after which they can alter security configuration and policy on a Security Management or Multi-Domain Management server. Exploitation requires the management server to be reachable from the internet with no restrictions on trusted GUI clients. The same update fixes a second critical authentication bypass and a Gaia Portal issue letting read-only users run commands as root.

Check
Install the July 22 Jumbo hotfix on Security Management and Multi-Domain Management servers, then restrict trusted GUI clients to approved addresses and firewall management access to known sources.
Affected
Organizations running Check Point Security Management or Multi-Domain Management with the console reachable from the internet (CVE-2026-16232); attackers gain administrator access and can rewrite the security policy protecting the network.
Fix
Apply the hotfix, limit trusted clients to specific addresses, keep management interfaces off the public internet, and review policy changes and administrator logins for unauthorized modifications.

Attackers exploit Windmill flaw to read server files and reach superadmin access

VulnCheck reports active exploitation of a path traversal flaw in Windmill, an open source platform for building internal tools, jobs, and workflows. CVE-2026-29059 lets an unauthenticated attacker read arbitrary files through the log file endpoint, and while observed attempts included reading the password file, the higher value target is the superadmin secret. Where that is configured, an attacker can authenticate as a super administrator and run arbitrary code through the job preview API. VulnCheck counted roughly 170 exposed instances across 24 countries, including deployments reachable through a proxy path rather than directly.

Check
Update Windmill to a fixed release, confirm whether any instance was reachable from the internet, and treat the superadmin secret and any credentials stored in configuration as exposed.
Affected
Organizations running internet-reachable Windmill deployments (CVE-2026-29059); unauthenticated attackers read server files, and where the superadmin secret is set, escalate to full administrative access and code execution.
Fix
Patch to the fixed version, rotate the superadmin secret and stored credentials, keep internal automation platforms off the public internet or behind authentication, and review logs for file read attempts.

Attackers steal SharePoint machine keys in one request after exploit code goes public

Attackers began exploiting a critical Microsoft SharePoint flaw within days of a working proof-of-concept appearing publicly. CVE-2026-50522 is a deserialization of untrusted data issue rated 9.8 that lets a remote attacker run code on on-premises SharePoint without authentication, and Microsoft patched it in the July updates while marking exploitation as more likely rather than confirmed. Offensive security firm watchTowr reports active attacks against on-premises deployments, with attackers pulling SharePoint machine keys in a single request. Those keys let an attacker forge authentication tokens and impersonate users, so access survives patching. It is the third SharePoint flaw to see exploitation this month.

Check
Apply July's SharePoint updates, then rotate machine keys on any on-premises server that was internet-reachable, since patching alone does not evict an attacker who already pulled them.
Affected
Organizations running on-premises SharePoint Server 2016, 2019, or Subscription Edition (CVE-2026-50522); unauthenticated attackers run code and steal machine keys that let them forge tokens and keep access after patching.
Fix
Patch, rotate machine keys and any credentials the server handled, hunt for web shells and forged token use, and restrict internet exposure of on-premises SharePoint deployments.

Critical ServiceNow AI Platform flaw now exploited in attacks

A critical flaw in the ServiceNow AI Platform is now being exploited in attacks. ServiceNow disclosed CVE-2026-6875 on July 13 in advisory KB3137947, describing it as a sandbox escape that lets an attacker bypass intended platform restrictions and execute code, and noting that exploitation does not require authentication. The AI Platform underpins much of the company's IT service management and workflow tooling, and the flaw affects both hosted and self-hosted deployments. ServiceNow deployed fixes to its hosted instances and released updates for self-hosted customers. Because these instances commonly connect to identity systems, cloud services, and endpoint management tools, a compromised one is a strong pivot point.

Check
Confirm your ServiceNow family release includes the fix for this flaw, prioritize self-hosted and internet-reachable instances, and review platform and AI feature logs for anomalous activity.
Affected
Organizations running unpatched ServiceNow AI Platform deployments (CVE-2026-6875), hosted or self-hosted; unauthenticated attackers can escape the sandbox and run code on a platform wired into identity, cloud, and endpoint systems.
Fix
Apply the fixed release for your family, verify hosted instances received the update, restrict instance exposure, and rotate integration tokens if compromise is suspected, while monitoring for unusual record changes.

SonicWall SMA1000 remote-access appliances hit by exploited zero-day flaws

SonicWall is warning that two flaws in its SMA1000 remote-access appliances are being actively exploited as zero-days, and has released hotfixes. CVE-2026-15409 is an unauthenticated server-side request forgery bug in the appliance's WorkPlace interface that lets an attacker make the device send requests to internal systems, turning an edge gateway into a pivot point. CVE-2026-15410 is a code-injection flaw in the management console that lets an administrator run operating-system commands, and SonicWall rates the overall advisory a top CVSS score of 10.0. Both were added to CISA's exploited-vulnerabilities catalog, with a federal deadline of July 17. Because exploitation is confirmed, any unpatched appliance should be treated as potentially compromised.

Check
Identify all SonicWall SMA1000 appliances, including standby and disaster-recovery nodes, apply the hotfix immediately, and review authentication logs, new accounts, outbound connections, and configuration changes for signs of intrusion.
Affected
Organizations running SonicWall SMA1000 remote-access appliances (CVE-2026-15409, CVE-2026-15410); attackers are actively exploiting the flaws, and the request-forgery and code-injection bugs could be chained to reach and run commands on internal systems.
Fix
Apply SonicWall's hotfix now, restrict management interfaces to trusted networks until patched, and because exploitation is confirmed, run a compromise assessment and assume unpatched appliances may already be backdoored.

CISA adds actively exploited Cisco IOS flaw to its must-patch catalog

CISA has added a Cisco IOS vulnerability to its Known Exploited Vulnerabilities catalog after confirming it is being used in real attacks, requiring federal agencies to patch it under a binding deadline. Cisco IOS and IOS XE run the routers and switches behind many enterprise and service-provider networks, so a flaw here can give attackers a foothold deep in the network path. The listing lands amid heightened warnings, including a joint US-and-allies advisory this week urging better router hygiene against Russian state-sponsored targeting of network devices. Network gear is attractive because it often sits unmonitored, stays online for years, and rarely runs endpoint security; timely patching is the main defense.

Check
Identify Cisco IOS and IOS XE devices, check them against Cisco's advisory for the newly listed flaw, and prioritize patching internet-facing and edge devices while reviewing configurations and logs for tampering.
Affected
Organizations running affected Cisco IOS or IOS XE network devices, especially internet-facing routers and switches; active exploitation means unpatched devices are at real risk of compromise deep in the network path.
Fix
Apply Cisco's fixed software promptly, restrict and monitor management interfaces, follow current router-hygiene guidance against state-sponsored targeting, and inspect device configurations and logs for signs of unauthorized changes.

Lone operator exploited Langflow flaws to steal AI and cloud keys across tenants

Sysdig detailed a financially motivated operator who chained two Langflow vulnerabilities to raid the AI orchestration platform for credentials, part of why CISA just added one of them to its exploited-vulnerabilities catalog. Using a cross-tenant access flaw (CVE-2026-55255), the attacker ran flows belonging to other tenants to steal their large language model provider keys and AWS keys, while a separate unauthenticated code-execution flaw (CVE-2026-33017) took over the host itself. The activity, observed in late June against an internet-exposed Langflow instance, followed a methodical pattern of reconnaissance, flow enumeration, and credential theft. It underscores that AI orchestration platforms concentrate valuable secrets and are increasingly a direct target once left exposed online.

Check
Identify any internet-exposed Langflow instances, confirm they are patched against the recent flaws, restrict them from public access, and review logs for cross-tenant flow access and unexpected outbound connections.
Affected
Organizations running exposed or unpatched Langflow (CVE-2026-55255, CVE-2026-33017); attackers can execute other tenants' flows to steal AI and cloud keys and run code on the host, harvesting concentrated credentials.
Fix
Patch Langflow, keep it off the public internet, rotate any potentially exposed AI provider and cloud keys, apply least privilege and short-lived credentials, and monitor for cross-tenant access and credential-harvesting behavior.

Attackers now exploiting a critical ColdFusion flaw Adobe patched last week

One of the critical ColdFusion vulnerabilities Adobe patched last week is now being exploited in the wild. The flaw, CVE-2026-48282, is a path-traversal issue rated 10.0 that lets an attacker run arbitrary code on a ColdFusion server, and it was among seven top-severity bugs Adobe fixed in ColdFusion 2025 and 2023. Adobe had flagged the update as high priority given ColdFusion's history as an attacker and ransomware target, and exploitation has followed quickly. Organizations that had not yet applied the update are now in an active-threat window, especially any ColdFusion servers reachable from the internet, which are the most exposed to opportunistic attacks.

Check
Confirm whether your ColdFusion 2025 and 2023 servers have last week's update applied, prioritize any that are internet-facing, and review logs and the filesystem for signs of exploitation or web shells.
Affected
ColdFusion 2025 and 2023 servers still missing last week's update (CVE-2026-48282); an attacker can use the path-traversal flaw to run code on the server, and exploitation is now underway.
Fix
Apply ColdFusion 2025 Update 10 and 2023 Update 21 immediately, restrict ColdFusion from direct internet exposure, and run a compromise assessment on any server that was unpatched while exploitation was occurring.

Critical Oracle E-Business Suite flaw now exploited for unauthenticated takeover

Attackers have begun exploiting a critical flaw in Oracle E-Business Suite, the financial and operations platform used by large enterprises, threat intelligence firm Defused reports. The bug (CVE-2026-46817), rated 9.8, sits in the File Transmission component of Oracle Payments and lets an unauthenticated attacker with HTTP access take over the system through a low-complexity attack. Oracle patched it in its May 2026 update, but exploitation began over the weekend despite no public proof-of-concept existing, meaning attackers built their own. Observed payloads attempt to read sensitive system files. Shadowserver tracks more than 450 EBS instances exposed online, many in North America and Asia, with unknown numbers still unpatched.

Check
Identify internet-facing Oracle E-Business Suite instances, confirm whether the May 2026 Critical Patch Update is applied, and review logs for suspicious requests to the Payments component and unexpected system-file access.
Affected
Oracle E-Business Suite versions 12.2.3 through 12.2.15 with the Payments component reachable over HTTP (CVE-2026-46817); unauthenticated attackers can fully compromise the system, and a private exploit is already in use.
Fix
Apply Oracle's May 2026 Critical Patch Update immediately, restrict EBS access to trusted networks, and run a compromise assessment if patching was delayed, since exploitation is underway without public exploit code.
