Summary

CVE-2026-34362 is a medium-severity Insufficient Session Expiration (CWE-613) vulnerability in Wwbn Avideo. Its CVSS base score is 5.4 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 16th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-12 (Session Termination) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `verifyTokenSocket()` function in `plugin/YPTSocket/functions.php` has its token timeout validation commented out, causing WebSocket tokens to never expire despite being generated with a 12-hour timeout.…

more

This allows captured or legitimately obtained tokens to provide permanent WebSocket access, even after user accounts are deleted, banned, or demoted from admin. Admin tokens grant access to real-time connection data for all online users including IP addresses, browser info, and page locations. Commit 5d5237121bf82c24e9e0fdd5bc1699f1157783c5 fixes the issue.

MITRE ATT&CK Enterprise TechniquesAI

T1078 Valid Accounts Stealth
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1133 External Remote Services Persistence
Adversaries may leverage external-facing remote services to initially access and/or persist within a network.
Why these techniques?

Insufficient WebSocket token expiration (CWE-613) directly enables indefinite use of captured/valid tokens for remote access (T1078 Valid Accounts) via the platform's external WebSocket service (T1133 External Remote Services), even post-account changes.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces session/token termination after the defined 12-hour validity window or account status changes, eliminating the permanent WebSocket access caused by the commented-out timeout check.

prevent

Requires proper authenticator (token) lifecycle management including expiration, revocation, and invalidation when user accounts are deleted, banned, or demoted, directly blocking reuse of stale admin tokens.

prevent

Enforces access decisions on every WebSocket request by validating token currency and current user privileges before granting real-time connection data exposure.

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-05 mostly match
prevents

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.

PR.AA-03 partial match
prevents

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

none

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
