Description
A vulnerability has been found in AeternaLabsHQ PullMD 3.2.0. This impacts an unknown function of the file /api of the component REST API Endpoint. The manipulation of the argument url leads to server-side request forgery. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 3.3.0 will fix this issue. The identifier of the patch is 96448894cc93ccecb0bdcbf263a9d25390a8455e. Upgrading the affected component is advised.
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-2026-76795 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-2026-76795 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-2026-76795. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
