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
|
|
impact: |
|
|
Successful exploitation of this vulnerability can lead to unauthorized access to internal resources, potential data leakage, and further attacks on the system.
|
|
remediation: |
|
|
Upgrade Gitlab CE/EE to a version that is not affected by the vulnerability (10.6 or higher).
