CVE-2026-59808
HIGHCVE-2026-59808 is a high-severity (CVSS 8.8) Missing Authentication vulnerability. O3 Security confirms whether CVE-2026-59808 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId() returns video_id_hash credentials for any video by encoder_queue_id without ownership verification, and useVideoHashOrLogin() converts this hash into passwordless login as the video owner. Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.
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-2026-59808 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-2026-59808 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-2026-59808. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
