Summary

CVE-2025-56643 is a critical-severity Insufficient Session Expiration (CWE-613) vulnerability in Requarks Wiki.Js. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 29th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-56643 is a critical vulnerability in Requarks Wiki.js version 2.5.307, where the application does not properly revoke or invalidate active JWT tokens upon user logout. As a result, previously issued tokens remain valid and can be reused to access the system even after logout, undermining session integrity and enabling potential unauthorized access if a token is compromised. The flaw exists in the authentication resolver logic and impacts both the GraphQL endpoint and the logout mechanism. It is associated with CWE-613 and carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to network accessibility, low complexity, and no privileges or user interaction required.

Any network-based attacker can exploit this vulnerability without privileges or user interaction by obtaining a valid JWT token, such as through interception, theft, or prior compromise. With the token in hand, the attacker can authenticate and access protected resources indefinitely, bypassing the logout process and maintaining unauthorized persistence in the system. This leads to high impacts on confidentiality and integrity, allowing data exfiltration, modification, or other malicious actions under the victim's session context.

Mitigation guidance and additional details are available in the advisory referenced at https://github.com/0xBS0D27/CVE-2025-56643, published on 2025-11-18.

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.
T1550 Use Alternate Authentication Material Lateral Movement
Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.
T1550.004 Web Session Cookie Lateral Movement
Adversaries can use stolen session cookies to authenticate to web applications and services.
T1563 Remote Service Session Hijacking Lateral Movement
Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
