CVE-2026-86187
MEDIUMCVE-2026-86187 is a medium-severity (CVSS 5.9) Insufficient Random Values vulnerability. O3 Security confirms whether CVE-2026-86187 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
WWBN AVideo generates passwords for external-login accounts using rand() instead of a cryptographic generator, producing only 31-bit integers. Attackers with access to password hashes can recover plaintext passwords in minutes through offline brute-force attacks due to unsalted MD5-based hashing.
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-2026-86187 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-2026-86187 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-2026-86187. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
