Q1What is this vulnerability? (Essence + Consequences)
đ¨ **Essence**: GitLab allows pipelines to run on **any branch** due to a logic flaw. đ **Consequences**: Unauthorized code execution, potential data theft, and system compromise.âŚ
đĄď¸ **Root Cause**: **CWE-306** (Missing Authentication for Critical Function). The flaw lies in insufficient access control, allowing users to trigger pipelines on branches they shouldn't have access to.
Q3Who is affected? (Versions/Components)
đŚ **Affected Versions**:
⢠GitLab **12.5** to **17.2.9**
⢠GitLab **17.3** to **17.3.5**
⢠GitLab **17.4** to **17.4.2**
â ď¸ Check your version immediately!
Q4What can hackers do? (Privileges/Data)
đ **Attacker Capabilities**: With low privileges, hackers can execute arbitrary code via pipelines. This leads to **High** Confidentiality and Integrity impact. They can steal secrets or modify code silently.
Q5Is exploitation threshold high? (Auth/Config)
đ **Exploitation Threshold**: **Low**. Requires **Low** Attack Complexity and **Low** Privileges (PR:L). No user interaction (UI:N) needed. It's a remote, network-accessible flaw.
Q6Is there a public Exp? (PoC/Wild Exploitation)
đŤ **Public Exploit**: **No**. The `pocs` array is empty. While HackerOne reports exist, no public PoC or wild exploit is currently available in the provided data.
Q7How to self-check? (Features/Scanning)
đ **Self-Check**:
1. Verify your GitLab version against the affected list.
2. Audit branch protection rules.
3. Check if pipelines can be triggered on restricted branches by non-admin users.
Q8Is it fixed officially? (Patch/Mitigation)
â **Official Fix**: **Yes**. The vulnerability is patched in versions **17.2.10+**, **17.3.6+**, and **17.4.3+**. Upgrade immediately to the latest stable release.
Q9What if no patch? (Workaround)
đ ď¸ **No Patch?**: Enforce strict **Branch Protection Rules**. Disable pipeline execution on protected branches for non-maintainers. Implement strict RBAC (Role-Based Access Control) as a temporary mitigation.
Q10Is it urgent? (Priority Suggestion)
đĽ **Urgency**: **HIGH**. CVSS Score indicates **Critical** impact on Confidentiality and Integrity. With Low exploitation difficulty, patch as soon as possible to prevent unauthorized code execution.
