Exploited Metabase zero-day gives unauthenticated attackers admin and database credentials

Metabase warned that a critical zero-day in its open-source business intelligence platform was exploited in the wild for data theft. Scored 10.0 and tracked only as GHSA-vwf4-m7j8-wcjf with no CVE assigned, so scanners relying on the national database will not flag it, the flaw is an unauthenticated SQL injection in the password-reset endpoint. A remote attacker with no credentials injects SQL into the application database, gains administrator access, and can steal the stored credentials for every database the instance connects to, then read and export their data. Metabase Cloud was attacked from around August 3 and is already patched; self-hosted versions 1.58 and later must upgrade.

Check
Upgrade self-hosted Metabase to the fixed release for your branch immediately, and if the reset-password endpoint was internet-reachable, treat the instance and all connected database credentials as compromised.
Affected
Organizations running self-hosted Metabase 1.58 or later; an unauthenticated attacker can gain admin access and steal credentials for every connected database, and it is exploited with no CVE for scanners to catch.
Fix
Patch to the safe release, clear the session table to revoke sessions, rotate credentials for all connected databases, audit API keys and admin accounts, and block the reset-password endpoint if unpatched.

Progress Kemp LoadMaster command injection flaw added to KEV after active exploitation

CISA added a critical Progress Kemp LoadMaster flaw to its Known Exploited Vulnerabilities catalog after reports of active exploitation. Tracked as CVE-2026-8037 and scored 9.6, it is a command injection bug that lets an unauthenticated attacker run arbitrary commands on the load balancer appliance through unsanitized input in several command endpoints. watchTowr traced it to improper handling of user input in a quote-escaping function. Telemetry recorded 792 exploitation attempts over 41 days from 65 addresses across 18 countries, with activity as recent as early August. Federal agencies were directed to patch by August 10, a useful signal of urgency for everyone else.

Check
Patch Progress Kemp LoadMaster appliances to the fixed release now, and because the appliance sits inline with traffic, review it for signs of command execution and unexpected configuration changes.
Affected
Organizations running unpatched Progress Kemp LoadMaster (CVE-2026-8037); an unauthenticated attacker can execute arbitrary commands on an appliance that sits inline with network traffic, and exploitation is ongoing.
Fix
Apply the vendor patch, restrict management access to the appliance, hunt for unauthorized commands and configuration changes, and rotate any credentials the load balancer stored or handled.

Cisco patches critical SD-WAN and IOS XE flaws with no available workarounds

Cisco released fixes for twelve flaws in Catalyst SD-WAN and IOS XE software, including three rated 9.9 and a command-injection issue rated 9.8. The three critical SD-WAN flaws, CVE-2026-20303, CVE-2026-20304, and CVE-2026-20310, stem from improper input validation, access control, and file-path handling in software that centrally controls a network. Cisco found them through internal testing that included frontier AI models and is not aware of exploitation, but there are no workarounds, so patching is the only remediation. Cisco also patched a management-controller flaw with public exploit code that lets a low-privileged user reach root.

Check
Upgrade Catalyst SD-WAN and IOS XE to the fixed releases Cisco lists, since there are no workarounds, and prioritize the management-controller flaw that already has public exploit code.
Affected
Organizations running affected Cisco Catalyst SD-WAN or IOS XE (CVE-2026-20303, CVE-2026-20304, CVE-2026-20310); the flaws affect software that centrally controls the network, and no workarounds exist.
Fix
Apply Cisco's fixed software, restrict access to network management interfaces, and treat the management-controller flaw with public proof-of-concept code as a priority since it reaches root.

18-year-old Linux SCTP flaw gives local root and can escape containers

Tencent researchers disclosed SCTPhantom, a use-after-free flaw in the Linux kernel's SCTP networking code that lets a local user gain root and, in some configurations, escape a container to the host. Tracked as CVE-2026-64564, the bug is in the protocol's dynamic address reconfiguration handling and traces to code introduced around 2008, making it roughly 18 years old. It is local rather than remote and needs SCTP reachable on the target, which limits exposure, but where those conditions hold the researchers gained root on several major distributions. It was found by an AI-assisted kernel research pipeline, the latest long-dormant kernel bug surfaced that way this year.

Check
Update to a fixed kernel, checking your distribution's tracker rather than the version string since vendors backport, and where SCTP is not needed, block the module to remove the attack surface.
Affected
Linux systems with SCTP reachable and an unpatched kernel (CVE-2026-64564); a local user can gain root, and in some container configurations escape to the host, though remote exploitation is not possible.
Fix
Apply the distribution kernel update and reboot, disable the SCTP module where unused, and tighten container policies that grant network and packet-socket capabilities to untrusted workloads.

WordPress pre-auth login XSS can chain to full server takeover

WordPress patched a pre-authentication reflected cross-site scripting flaw in the login screen that researchers showed can chain into PHP code execution and full server takeover, naming the chain XSS2Shell. Tracked as CVE-2026-64638 and scored 8.9, the cross-site scripting bug affects all WordPress versions and needs no login to trigger. On its own it runs script in a visitor's browser, but when a logged-in administrator is lured to an attacker-controlled page, the chain can reach code execution on the server. Because WordPress runs a large share of the web, a flaw affecting every version and needing no authentication has broad reach.

Check
Update WordPress to the patched release across every site, including forgotten and staging installs, and put a web application firewall in front of internet-facing sites.
Affected
All WordPress sites on versions before the fix (CVE-2026-64638); an unauthenticated attacker can run script in the login page, and luring an administrator to a crafted page can chain to code execution.
Fix
Apply the WordPress update, confirm automatic updates ran, use a web application firewall, and remind administrators to avoid unexpected links, since the chain to code execution runs through an admin's browser.

Exact Sciences breach exposes data of nearly 11 million in extortion campaign

Data from a breach at cancer-screening company Exact Sciences, now part of Abbott, was indexed by Have I Been Pwned with about 10.9 million unique email addresses. The extortion group ShinyHunters claimed the intrusion, saying it reached internal legacy systems and then pivoted from a corporate single-sign-on account into connected cloud services such as Microsoft 365, Salesforce, and others to steal data. It is part of a wider ShinyHunters wave hitting medical-technology companies. Abbott is investigating and disputed the attacker's characterization of some data. The pattern, one stolen sign-on unlocking many linked services, is now a recurring route to large healthcare breaches.

Check
People who used Exact Sciences services should watch for breach notices and health-themed phishing, and organizations should map which cloud services a single corporate sign-on can unlock.
Affected
Roughly 11 million people whose data sat in Exact Sciences systems and connected cloud services; attackers used one corporate sign-on to reach linked platforms, a pattern behind repeated large medical breaches.
Fix
Enforce phishing-resistant MFA on single-sign-on, scope what each connected cloud app can access, monitor for bulk exports across integrated services, and prepare for extortion-driven leaks of healthcare data.

A single GitHub issue could reach CI secrets across major AI coding agents

Novee Security showed at Black Hat that a GitHub issue opened by an account with no repository access could reach the CI runners behind major AI coding agents in their default configurations, tested against Claude Code, Gemini CLI, and Codex. The strongest, a Gemini CLI container-launcher command injection scored 10.0, runs code on the CI host before the sandbox starts. In Claude Code, a validator that stripped quoted text let a payload in a Git flag reach the runner, and a separate flaw leaked an API key through a download counter. Untrusted issue content reaching an agent that holds secrets and tools in the same runtime is the shared weakness.

Check
Update Gemini CLI to 0.39.1 and Claude Code to 2.1.163, and review any workflow where an AI agent runs automatically on issues or pull requests from untrusted users.
Affected
Teams running AI coding agents on public repositories in default configurations (CVE-2026-12537, CVE-2026-54316); an unprivileged GitHub issue or pull request can reach CI runners and expose workflow secrets and tokens.
Fix
Patch the agents, restrict their tools with allowlists rather than blocklists, give triage and review agents read-only tokens, and keep separate agent runs from sharing writable directories.

Atlassian Rovo assistant can be tricked into leaking Jira and Confluence data

Two security firms showed that Atlassian's Rovo AI assistant can be steered by hidden instructions into collecting Jira and Confluence data a signed-in user can access and sending it to an outside server. PromptArmor concealed the instructions in a document Rovo reads, so asking it to organize tickets makes it gather internal data and leak it through a URL request, with no approval step and even with web search disabled. Varonis used a chat URL parameter to preload instructions, so one click ran them with the user's privileges. Atlassian fixed the link-based path server-side, but the content-based path was not confirmed fixed at disclosure.

Check
Scope which users, groups, and apps can use Rovo and which data it can reach, and treat documents and pages it processes as capable of carrying hidden instructions.
Affected
Organizations using Atlassian Rovo across Jira and Confluence; hidden instructions in content the assistant reads can make it exfiltrate tickets, pages, and connected data under a legitimate user's access.
Fix
Limit Rovo's access and the connectors it can reach, restrict who can enable it, monitor for unusual outbound requests from the assistant, and treat all content it ingests as untrusted input.

Critical Terraform MCP flaw lets one user's cloud token serve another's requests

HashiCorp, Veeam, and Django patched critical flaws the same week, led by a top-severity bug in HashiCorp's Terraform MCP Server, which connects AI assistants to Terraform. Tracked as CVE-2026-16498 and scored 10.0, it is a cross-tenant flaw in the server's multi-user HTTP mode: its cache looked up clients by session identifier alone, without binding a cached client to the token that created it, so anyone who obtained another user's session ID could run Terraform actions with that user's credential. Only the shared HTTP deployment is affected, not local single-user mode. Veeam separately fixed an unauthenticated console flaw exposing agent credentials, and Django a code-execution bug in spatial queries.

Check
Update Terraform MCP Server to 1.1.0 or later, Veeam Service Provider Console to 9.3.0.35057, and Django to 6.0.8 or 5.2.17, prioritizing multi-user Terraform MCP deployments.
Affected
Teams running Terraform MCP Server in shared HTTP mode (CVE-2026-16498), Veeam Service Provider Console, or affected Django; the Terraform flaw lets one tenant's token be reused for another's requests.
Fix
Patch all three, run MCP servers in single-user stdio mode where possible, bind sessions to their credentials, restrict access to shared MCP HTTP listeners, and rotate tokens that may have been reused.

OVSwrap kernel flaw gives local users root on most Linux distributions

A researcher disclosed OVSwrap, a Linux kernel flaw in the Open vSwitch datapath that lets an ordinary local user gain root, and published a working exploit covering roughly 800 builds. Tracked as CVE-2026-64531, it is an integer wraparound in how Open vSwitch handles internally generated network action streams, giving a deterministic memory-corruption path. The attacker needs no existing switch, no running daemon, and no special privileges: where unprivileged user namespaces are enabled, they create a private namespace, gain network capabilities inside it, and reach the vulnerable code. The module can even auto-load on demand, so an empty module list does not mean safety. Default configurations of most major distributions tested as exploitable.

Check
Install the patched vendor kernel, which upstream fixed on July 24, and where you cannot patch immediately, disable unprivileged user namespaces to cut off the main path to the flaw.
Affected
Most default-configured Linux systems with the Open vSwitch module available and unprivileged user namespaces enabled (CVE-2026-64531); an ordinary local user can corrupt kernel memory and gain root, with a public exploit available.
Fix
Apply patched kernels and reboot, restrict unprivileged user namespaces where feasible, and prioritize shared and multi-tenant hosts, since any local foothold from another flaw or stolen access can escalate to full control.
