CVE-2026-84480 in AVideo
Summary
by MITRE • 09/02/2026
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.

The vulnerability identified in WWBN AVideo represents a critical failure in session management and cryptographic state validation, specifically within the userRecoverPassSave.json.php endpoint. This flaw stems from an insufficient verification of the expiration timestamp associated with password recovery tokens. In secure authentication systems, temporary credentials such as reset tokens must possess a strictly enforced time-to-live (TTL) to limit the window of opportunity for malicious actors. However, in this implementation, the server-side logic fails to compare the current system time against the token's designated expiry date before processing the password change request. This oversight effectively nullifies one of the primary security controls designed to mitigate credential theft and unauthorized account takeover attempts.
From a technical perspective, the absence of expiration validation transforms what should be a short-lived, single-use or limited-time credential into an indefinitely valid secret. If an attacker manages to intercept or obtain a recovery token through methods such as cross-site scripting (XSS), server-side request forgery (SSRF), or insecure direct object references, they are not constrained by temporal boundaries. The application accepts the token regardless of how much time has passed since its issuance. This behavior violates fundamental principles of secure design regarding state management and session validity, allowing for persistent access even after the intended recovery window has closed.
The operational impact of this vulnerability is severe, as it directly facilitates account takeover attacks. An attacker who possesses a valid but expired token can reset the password associated with any user account that initiated a recovery request. This grants the adversary full administrative or standard user privileges depending on the compromised account's role within the AVideo platform. Such access allows for unauthorized content manipulation, data exfiltration of sensitive user information, and potentially further lateral movement if the compromised account has elevated permissions. The ability to reset passwords indefinitely means that even long-abandoned recovery attempts remain exploitable, significantly expanding the attack surface over time.
This vulnerability aligns with CWE-613, which classifies insufficient session expiration as a distinct category of security weakness. It also maps closely to MITRE ATT&CK technique T1078, specifically valid accounts and potentially T1528 for stealing application access tokens if the token mechanism is viewed analogously to OAuth flows. The lack of temporal validation ensures that the integrity of the authentication workflow is compromised at a foundational level.
To mitigate this risk, immediate remediation requires implementing strict server-side expiration checks on all password recovery endpoints. Developers must ensure that every generated token includes an embedded or database-stored timestamp and that the application validates this timestamp against the current time before proceeding with any credential modification logic. Additionally, tokens should be invalidated immediately after successful use to prevent replay attacks. Implementing rate limiting on password reset requests can further reduce the risk of brute-force enumeration attempts targeting these endpoints. Regular security audits focusing on session management practices are recommended to identify similar flaws across other authentication flows within the application.
