Description
A vulnerability was detected in GH05TCREW PentestAgent up to cf882dabea3ed91cef016cdd115e5426315665a2. This vulnerability affects the function run_task of the file interface/main.py of the component MCP HTTP Server. Performing a manipulation results in os command injection. The attack is possible to be carried out remotely. The exploit is now public and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The pull request to fix this issue awaits acceptance.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-90617 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-90617 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-90617. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
