CVE-2026-86190
CRITICALCVE-2026-86190 is a critical-severity (CVSS 9.1) Information Exposure vulnerability. O3 Security confirms whether CVE-2026-86190 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
WWBN AVideo contains a broken access control vulnerability in videoViewsInfo endpoints that returns complete user records including password hashes, recovery tokens, and live session identifiers to unauthenticated callers when a hash parameter is provided. Attackers can use the disclosed session identifier to hijack viewer sessions, including administrator accounts, and obtain sensitive personal data for all video viewers.
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-2026-86190 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-2026-86190 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-2026-86190. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
