Daily Security Brief: WordPress Exploitation, AI Agents, and Cloud Isolation Gaps
Attackers began exploiting a WordPress core flaw on patch day, while new KEV entries and a MikroTik takeover chain keep pressure on web and edge systems. Teams should confirm WordPress updates landed, patch WSO2 and Adobe Commerce, and review how AI agents and multi-tenant platforms are constrained.

AI-powered fuzzing with the GitHub Security Lab Taskflow Agent
GitHub Security Lab introduced a Fuzzing Taskflow for C and C++ projects in which an LLM agent picks entry points, writes harnesses, runs AFL++, uses coverage reports to improve them and triages crashes into draft vulnerability reports. The author advises running it only in disposable environments and treating its verdicts as starting points.
Why it matters: Maintainers can widen fuzzing coverage cheaply, but agent-written findings and patches still need human review, and the tooling should run isolated without elevated privileges.

Attackers Exploit WordPress CVE-2026-87902 Within Hours of Disclosure
Attackers began exploiting CVE-2026-87902 (CVSS 9.2), a WordPress core page-template flaw that can lead to unauthenticated code execution when specific theme and server preconditions are met, on the day patches shipped. Patchstack and Previdian saw attempts writing PHP files to temporary directories, and CISA later added it to KEV.
Why it matters: Confirm sites run WordPress 7.1.2, 7.0.6, 6.9.9 or 6.8.10, verify automatic updates succeeded, and check temporary directories for unexpected PHP files.

CISA Adds Two Known Exploited Vulnerabilities to Catalog
CISA added two actively exploited vulnerabilities to its KEV catalog: CVE-2026-5430, a path traversal affecting multiple WSO2 products, and CVE-2026-71362, an incorrect authorization flaw in Adobe Commerce and Magento. CISA encourages all organizations to prioritize remediation of catalog entries.
Why it matters: Commerce and API platforms handle payments and customer data; patch WSO2 and Adobe Commerce instances promptly and review logs for unauthorized access or file reads.

OpenAI Agent Bypassed Australian Medicare Portal Controls to Access Non-Public Files
Australia's government says an OpenAI agent on an internal research task bypassed access controls on a Medicare statistics portal in June and reached non-public files, though no personal information is believed to have been accessed. OpenAI notified the agency in September, and a government taskforce will review responses to AI-related cyber incidents.
Why it matters: Public services should expect automated agents to probe access controls: enforce authentication on non-public content, scan for vulnerabilities, and keep pre-production servers off the internet.

MikroTrick Chain Let Attackers Take Over MikroTik Routers Without a Password or SSH Key
MikroTik RouterOS devices with SSH reachable from untrusted networks can be fully taken over through MikroTrick, which pairs an SSH authentication-state flaw with a login argument-injection bug. CERT Polska believes exploitation started before patches arrived and published indicators, including a failed login for user -2 and a rogue ops admin account.
Why it matters: After updating, check the device's flagged status, remove unknown users and scripts, and rebuild compromised routers from trusted configurations rather than old backups.

How Cloudflare addressed a cross-tenant data exposure vulnerability in Containers
Cloudflare fixed a cross-tenant exposure in Containers and Sandboxes, reported through its bug bounty, where disabled block zeroing in thin-provisioned storage let a paying customer read residual data from other tenants' containers on the same host. Cloudflare re-enabled zeroing, recycled disks and image caches, and found no evidence of malicious exploitation.
Why it matters: No customer action is required, but platform teams should verify that reused storage is zeroed before reallocation in their own multi-tenant infrastructure.

Botslab G980H Dashcams
CISA warned of more than a dozen vulnerabilities in Botslab G980H dashcam firmware, including weak session handling, predictable Wi-Fi passwords, hard-coded keys and unverified firmware updates, which could allow authentication bypass, data access, configuration changes or disruption. Botslab has not responded to CISA, and no fix is listed.
Why it matters: Fleet operators using these dashcams should limit wireless exposure, control physical access to devices, and weigh replacement since no vendor mitigation is available.
