CISA KEV Advisory
GitLab Server-Side Request Forgery (SSRF) Vulnerability
GitLab contains a server-side request forgery (SSRF) vulnerability when requests to the internal network for webhooks are enabled.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
GitLab contains a server-side request forgery (SSRF) vulnerability that can be exploited when webhooks are enabled for requests to the internal network. This critical vulnerability has a CVSS score of 9.8 and an EPSS score of 0.73487, indicating a high likelihood of exploitation. Its inclusion in CISA's KEV confirms it is actively being exploited.
This vulnerability is actively exploited in the wild and is remotely exploitable due to its network-based attack vector and low attack complexity. Its presence in CISA's KEV confirms its active use by malicious actors.
Administrators should apply the latest security updates for GitLab to address this SSRF vulnerability. Review and restrict webhook configurations to prevent requests to internal networks.
Technical Analysis
CVE-2021-22175 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
CISA has added CVE-2021-22175 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
