CVE-2024-3114Network attack vector

Server slowdown via inefficient invalid-commit parsing

Published Aug 8, 2024 · Updated Aug 30, 2024

Regular-expression denial of service in GitLab CE/EE allows remote authenticated users to interrupt server processing by submitting invalid commits. The commit-parsing logic evaluates malformed, attacker-controlled commit data with an inefficient regular expression, causing excessive resource consumption; GitLab has not disclosed the specific function or pattern. An authenticated user must supply an invalid commit; affected releases are 11.10 through 17.0.5, 17.1 through 17.1.3, and 17.2 through 17.2.1, and the documented effect is reduced server availability rather than data exposure or modification.
