CVE-2025-68398: Weblate is vulnerable to RCE through Git config file overwrite

Weblate is a web based localization tool.

CVSS 9.1 Critical EPSS 0.8% · p56

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 0.8%, percentile 56: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 56% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
  • Needs an account (high (admin)). Exposure depends on who can log in.
  • Only applies if your dependency tree includes Weblate (PyPI) < 5.15.1, fixed in 5.15.1. Check your lockfile, including transitive dependencies.

What it is

Weblate is a web based localization tool. In versions prior to 5.15.1, it was possible to overwrite Git configuration remotely and override some of its behavior. Version 5.15.1 fixes the issue.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.

Exploitation and urgency

  • CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
  • CISA SSVC assessment: exploitation none, automatable no, technical impact total.
  • FIRST EPSS (model of 2026-10-21): 0.79% probability of exploitation activity in the next 30 days; percentile 56.
