gitlab-plugin is vulnerable to Server-Side Request Forgery (SSRF)
43
Medium Risk
This Affects:
gitlab-pluginTL;DR
A @DataBoundConstructor path in GitLab Plugin allows data-bound setters to overwrite global GitLab connection settings. Attackers able to submit certain forms can redirect requests to attacker-controlled URLs while reusing administrator-configured GitLab API tokens. The fix removes the @DataBoundConstructor annotation from that global configuration constructor.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and users can submit forms that bind GitLab plugin global configuration.

gitlab-plugin is vulnerable to Server-Side Request Forgery (SSRF) in versions 0.0.1 - 1.9.16.
How to fix this
Upgrade the org.jenkins-ci.plugins:gitlab-plugin library to the patch version.
