Description
WWBN AVideo (current e01e41ecc and earlier) contains a brute-force rate limiting bypass in enforceRateLimit(), which protects login.json.php and 13 other endpoints. The function stores its attempt counter via a cache layer (ObjectYPT::setCacheGlobal) that silently discards writes for any client identified as a bot by isBot(). Because isBot() treats a missing User-Agent header as a bot by default — and also matches common bot identifiers such as 'curl', 'bot', 'crawler', and 'spider' — the counter never increments for such clients, so the rate limit never fires. An unauthenticated attacker can therefore submit unlimited login attempts (e.g., by omitting the User-Agent header or using curl's default User-Agent), enabling unrestricted password-guessing attacks.
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-2026-82644 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-2026-82644 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-2026-82644. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
