GitLab: Improper Enforcement of Behavioral Workflow
CVE-2024-0410 is a high-severity improper enforcement of behavioral workflow vulnerability in GitLab, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists versions 16.7.6, 16.8.3, 16.9.1 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 0.46% 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 16.7.6 or 16.8.3 or 16.9.1, whichever matches your release line, or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Enforcement of Behavioral Workflow
