An issue has been discovered in GitLab CE/EE affecting all versions from 17.3 before 17.11.5…
CVE-2025-2938 is a high-severity vulnerability in GitLab, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 17.11.5, 18.0.3, 18.1.1 as the first without the flaw, so updating GitLab to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
