WWBN AVideo fails to validate password recovery token expiration in userRecoverPassSave.json.php, allowing attackers to use expired tokens to reset account passwords indefinitely. Attackers who obtain a recovery token can use it at any time to change the target account's password and gain full account access.
Articles & Coverage 1
AnalysisAI
Account takeover in WWBN AVideo is possible because userRecoverPassSave.json.php never checks whether a password-recovery token has expired, so any captured token stays valid forever. An attacker who obtains a recovery token for a target account can reset that account's password at an arbitrary later time and seize full control. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires possession of a valid password-recovery token for the target account issued through AVideo's recovery flow; the vulnerability removes the time limit on that token so it works even long after issuance via userRecoverPassSave.json.php. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base of 9.3 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H) reflects that once a token is held, resetting the password is a trivial unauthenticated network request yielding full confidentiality, integrity and availability impact over the victim account. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to the fixed AVideo release referenced in GHSA-j9p7-hm85-9v77 (the advisory is the authoritative source for the exact patched version, which was not included in the structured input, so confirm the tag there before deploying). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Assess your WWBN AVideo deployment for internet exposure; disable the password recovery feature if operationally feasible, or restrict it to administrator-only access. …
