AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L
Network-reachable but needs an authenticated account (PR:L) and attacker-uncontrollable conditions (AC:H); mass-assignment lets one user alter another's config, changing scope (S:C) with high C/I and limited availability impact.
Primary rating from Vendor (GitLab).

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.0 before 19.0.5, 19.1 before 19.1.3, and 19.2 before 19.2.1 that under certain conditions could have allowed an authenticated user to modify CI/CD configuration belonging to another user due to improper validation of user-supplied attributes when processing pipeline schedule inputs.
Articles & Coverage 2
AnalysisAI
Improper attribute validation in GitLab CE/EE (18.0 through 19.0.5, 19.1 through 19.1.3, 19.2 through 19.2.1) lets an authenticated user tamper with CI/CD configuration owned by another user by injecting user-controlled attributes into pipeline schedule input processing. Publicly available exploit code exists (HackerOne #3800511), though the flaw is not listed in CISA KEV and requires authentication plus high-complexity conditions to trigger. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated GitLab account (CVSS PR:L) that can submit pipeline schedule inputs, and the flaw is specifically triggered when GitLab processes user-supplied attributes during pipeline schedule input handling - the vulnerable surface is the pipeline schedule feature, so instances that do not expose scheduling to untrusted users are less exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 8.4 (AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L) reflects a network-reachable, low-privilege attack with no user interaction and a scope change, but crucially with high attack complexity - meaning special, attacker-uncontrollable conditions must hold, which tempers the raw severity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low-privileged authenticated account on a shared GitLab instance crafts a pipeline schedule request that injects extra attributes into the input processing, causing GitLab to associate or overwrite CI/CD configuration tied to another user. Public exploit material is referenced via HackerOne report #3800511, but the AC:H rating indicates the attacker must satisfy specific timing or state conditions for reliable success. |
| Remediation | Vendor-released patch: upgrade to GitLab 19.0.5, 19.1.3, or 19.2.1 (or later) depending on your branch, as documented at https://docs.gitlab.com/releases/patches/patch-release-gitlab-19-2-1-released/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all GitLab instances running affected versions (18.0-19.0.5, 19.1-19.1.3, 19.2-19.2.1) and restrict pipeline schedule modification permissions to pipeline owners pending patching. …
