Lifecycle Timeline
3DescriptionCVE.org
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.8 before 19.0.6, 19.1 before 19.1.4, and 19.2 before 19.2.2 that under certain conditions could have allowed an authenticated user to achieve remote code execution due to a path traversal vulnerability in the package registry.
AnalysisAI
Remote code execution in GitLab CE/EE package registry exposes instances across three active version branches to full host compromise by an authenticated low-privilege user. Path traversal (CWE-22) in the package registry component allows directory escape and arbitrary file write under certain server-side conditions, with CVSS scope change (S:C) confirming that impact extends beyond the GitLab application to the underlying host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated GitLab account with at least low-privilege access to the target instance (PR:L per CVSS vector) - anonymous or unauthenticated access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.5 base score reflects a serious network-accessible RCE with full C/I/A impact and scope change, tempered by High complexity (AC:H) and Low-privilege authentication requirement (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade immediately to one of the patched releases - 19.0.6, 19.1.4, or 19.2.2 - depending on your current version branch, as documented at https://gitlab.com/gitlab-org/gitlab/-/work_items/601596. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, enumerate all GitLab CE/EE instances across affected version branches and immediately disable package registry functionality or restrict access to explicitly trusted users only. …
