Description
WWBN AVideo through commit e01e41ecc (no patched version available) exposes get_api_preauthorize in plugin/API/API.php as a second, undocumented login path. Unlike get_api_signIn, which enforces a rate limit of 10 attempts per 5 minutes via checkRateLimit(), get_api_preauthorize performs the same credential check with no throttling for any client, allowing unlimited remote password guessing against arbitrary accounts, including admin. The endpoint also acts as a credential oracle: it returns the message "Invalid credentials" for both correct and incorrect passwords, while the users_id field in the response body discloses the authenticated identity (users_id:1 on success, users_id:0 on failure), and a correct password establishes a session cookie that remains usable for authenticated API requests. Together these issues permit unauthenticated brute-force account takeover.
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-2026-86729 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-2026-86729 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-2026-86729. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
