name: Gitlab CE/EE 10.5 - Server-Side Request Forgery
author: Suman_Kar,GitLab Red Team

description: |
GitLab CE/EE versions starting from 10.5 are susceptible to a server-side request forgery vulnerability when requests to the internal network for webhooks are enabled, even on a GitLab instance where registration is limited. The same vulnerability actually spans multiple CVEs, due to similar reports that were fixed across separate patches. These CVEs are:
- CVE-2021-39935
- CVE-2021-22214
- CVE-2021-22175

Upgrade Gitlab CE/EE to a version that is not affected by the vulnerability (10.6 or higher).
