Note: Failure to invalidate a session on log out allows an adversary who has compromised the session more time to take action on the compromised session than is necessary.

Referencias Descripción

CVE-2026-105690

Chain: auth-token was cleared on the browser after logout (CWE-602), but not revoked on the server-side (CWE-1465)

CVE-2019-12421

Chain: log out invalidated the session on the client side (CWE-602), but not the server side (CWE-1465)

Mitigaciones potenciales

Phases : Implementation
Ensure that user sessions are invalidated on the server-side after a client logs out or attempts to end their session. It is important that the server-side handles all session invalidation – including multiple tabs or windows, such as within a web browser - and does not rely on the client to remove or delete a session due to the possibility of adversaries capturing session identifiers or cookies for later reuse.

Notas de mapeo de vulnerabilidades

Justificación : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comentario : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Notas

This entry was created in CWE 5.0 to address known gaps in CWE coverage. It is not as complete as other new entries that were published in recent years. The CWE Team plans to work with the CWE community to make this entry more complete in later 5.x releases.
