Description
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in the LoginControl plugin PGP key endpoints that lack CSRF token validation. Attackers can craft malicious pages with image tags pointing to savePublicKey.json.php to replace a logged-in victim's PGP 2FA public key, causing lockout or enabling account takeover if the attacker knows the password.
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-2026-88870 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-2026-88870 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-2026-88870. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
