CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NSummary
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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Credential lifecycle management directly includes enforcing session expiration to prevent reuse.
Authorization policy enforcement and review covers terminating stale sessions to limit access scope.
Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

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