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.

Ubiquiti UniFi and Lantronix flaws now exploited; CISA sets June 26 deadline

CISA has confirmed active exploitation of four critical flaws in Ubiquiti UniFi OS and Lantronix EDS5000 devices, adding them to its Known Exploited Vulnerabilities catalog with a June 26 deadline for federal agencies. Three UniFi OS bugs (CVE-2026-34908, CVE-2026-34909, CVE-2026-34910), each rated 10.0, can be chained for unauthenticated remote code execution and root; attackers were seen creating rogue admin accounts. The Lantronix flaw (CVE-2025-67038) is an unauthenticated root command injection in the EDS5000 serial console server. Ubiquiti patched UniFi OS Server in version 5.0.8, and Lantronix in firmware 2.2.0.0R1. Compromised network appliances let attackers pivot deep into internal networks.

Check
Inventory Ubiquiti UniFi OS consoles and gateways and any Lantronix EDS5000 device servers, confirm their firmware versions, and review logs for unexpected admin accounts or commands, especially on internet-reachable management interfaces.
Affected
UniFi OS devices before Server version 5.0.8 (CVE-2026-34908, CVE-2026-34909, CVE-2026-34910) and Lantronix EDS5000 on firmware 2.1.0.0R3 (CVE-2025-67038); unauthenticated attackers can reach root and pivot inward.
Fix
Update UniFi OS to 5.0.8 or later and Lantronix EDS5000 to firmware 2.2.0.0R1 before the June 26 deadline, and restrict device management interfaces to trusted networks until patched.

Cisco Unified CM flaw now exploited to gain root on phone systems

A flaw in Cisco Unified Communications Manager, the system that runs enterprise phone and call infrastructure, is now being exploited in attacks. The bug (CVE-2026-20230) is a server-side request forgery that lets an unauthenticated attacker send a crafted HTTP request to write files onto the underlying system, which can then be used to escalate to root and fully take over the server. Cisco patched it on June 3 and rates it critical; public exploit code has been available since, and security firms now see active exploitation attempts. The flaw is only exploitable when the WebDialer service is enabled, which is not the default.

Check
Check whether your Cisco Unified CM or Session Management Edition deployments have the WebDialer service enabled and confirm the software version, then review system logs for unexpected file writes or webshells.
Affected
Cisco Unified CM and Unified CM SME with the WebDialer service enabled (CVE-2026-20230); version 14 before 14SU6 and version 15 before 15SU5, especially with management interfaces reachable by attackers.
Fix
Patch to Cisco Unified CM 14SU6 or apply the version 15 interim fix, or disable the WebDialer service if it is not needed, and restrict management interfaces to trusted networks.

Hackers mass-exploit Gravity SMTP WordPress flaw to steal email API keys

Attackers are mass-exploiting a flaw in Gravity SMTP, a WordPress email plugin installed on about 100,000 sites, to harvest credentials without any login. The bug (CVE-2026-4020) leaves a REST API endpoint with a permission check that always passes, so a single unauthenticated request returns a 365 KB system report containing API keys, secrets, and OAuth tokens for connected email services like Amazon SES, Mailjet, and Zoho, plus detailed software-stack information. Wordfence has blocked more than 17 million attempts, with activity spiking around June 6 and 7. A patch shipped in version 2.1.5, but updating does not revoke keys attackers may have already grabbed.

Check
Identify WordPress sites running Gravity SMTP at version 2.1.4 or earlier, and review web server access logs for requests to the /wp-json/gravitysmtp/v1/tests/mock-data endpoint, which indicate attempted or successful data exposure.
Affected
WordPress sites running Gravity SMTP through 2.1.4 with email integrations configured (CVE-2026-4020); exposed API keys and OAuth tokens let attackers abuse connected email services and map the site for follow-on attacks.
Fix
Update Gravity SMTP to 2.1.5 or later, then assume compromise: rotate all API keys, secrets, and OAuth tokens set in the plugin's email connectors, and block the published attacker IPs.

Splunk Enterprise flaw now exploited, added to CISA must-patch list

A critical Splunk Enterprise flaw disclosed earlier this month is now being exploited in the wild, and CISA has added it to its known-exploited list with a June 21 federal patch deadline. The bug (CVE-2026-20253, rated 9.8) is a missing-authentication issue in a PostgreSQL sidecar service: an unauthenticated, network-reachable attacker can create or truncate arbitrary files on the Splunk host, which can cascade into log corruption, broken monitoring, and remote code execution. Both Splunk and Resecurity have confirmed active exploitation, and a public proof-of-concept and Nuclei template exist. Because Splunk underpins many SOC and SIEM operations, a compromise can blind defenders.

Check
Identify Splunk Enterprise instances on 10.2 before 10.2.4 or 10 before 10.0.7, check whether the PostgreSQL sidecar endpoint is network-reachable, and review logs for path-traversal and unexpected PostgreSQL connections.
Affected
Splunk Enterprise 10.2 versions before 10.2.4 and 10 versions before 10.0.7 (CVE-2026-20253); instances whose PostgreSQL sidecar endpoint is reachable from untrusted networks are at highest risk.
Fix
Patch to Splunk Enterprise 10.2.4 or 10.0.7 immediately, or disable the PostgreSQL sidecar service as a temporary mitigation. Then run forensic triage for file tampering before assuming systems are clean.
