CVE-2026-24126: Weblate has an argument injection in management console

CriticalCVSS 9.1 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.51% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: weblate (PyPI) 5.16.0, 5.16.
  • Severity is disputed: the assigning authority (CNA) scores it 6.6, NVD 9.1.

Low priority for now. Upgrade to weblate (PyPI) 5.16.0, 5.16 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Weblate is a web based localization tool. Prior to 5.16.0, the SSH management console did not validate the passed input while adding the SSH host key, which could lead to an argument injection to `ssh-add`. Version 5.16.0 fixes the issue. As a workaround, properly limit access to the management console.
