CVE-2026-41519: CWE-613: Insufficient Session Expiration in WeblateOrg weblate
Weblate is a web based localization tool. Prior to version 5.17.1, when a user changes their password, browser sessions are correctly invalidated via "cycle_session_keys()", but DRF API tokens ("wlu_*" prefix) stored in "authtoken_token" are not revoked. This issue has been patched in version 5.17.1.
AI Analysis
Technical Summary
Weblate, a web-based localization tool, had an insufficient session expiration vulnerability (CWE-613) identified as CVE-2026-41519. Specifically, although password changes trigger invalidation of browser sessions via the cycle_session_keys() function, the Django REST Framework (DRF) API tokens stored in the authtoken_token table with the "wlu_*" prefix were not revoked. This allowed these tokens to remain valid after a password change, potentially enabling continued access. The vulnerability affects Weblate versions earlier than 5.17.1 and was addressed by patching in version 5.17.1.
Potential Impact
The vulnerability allows DRF API tokens to remain valid after a user changes their password, which could permit continued access using those tokens despite the password update. The CVSS score of 4.2 reflects a medium severity impact with limited confidentiality and integrity impact and no availability impact. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade Weblate to version 5.17.1 or later, where this vulnerability has been patched. Since this is an official fix, applying the update fully mitigates the issue. No additional mitigation steps are indicated.
