GitLab: Improper Handling of Parameters
CVE-2026-2370 is a high-severity improper handling of parameters 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 18.8.7, 18.9.3, 18.10.1 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 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update GitLab to 18.8.7 or 18.9.3 or 18.10.1, whichever matches your release line, or a later version.
