| 参考文献 | 説明 |
|---|---|
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) |
潜在的な緩和策
Phases : ImplementationEnsure 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.
脆弱性マッピングノート
理由 : 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.コメント : 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.
ノート
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.参考文献
