An issue was discovered in GitLab CE/EE affecting all versions starting from 11.10 prior to 17.0.6, 17.1 prior to 17.1.4, and 17.2 prior to 17.2.2, with the processing logic for parsing invalid commits can lead to a regular expression DoS attack on the server.
Solution:
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
