Description

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 16.11 before 18.7.6, 18.8 before 18.8.6, and 18.9 before 18.9.2 that could have allowed an authenticated user to cause a denial of service condition due to improper input validation on webhook custom header names under certain conditions.
