The improper authorization check permits the user to bypass the intended restriction, potentially enabling the deployment of code to environments that should only be accessed by higher\u2011privileged roles. The weakness is a classic checks\u2011before\u2011use error (CWE\u2011863). While it does not directly execute arbitrary code, the ability to reconfigure protect\u2011ed pipelines can lead to privilege escalation and unauthorized application deployments, harming confidentiality, integrity, and availability of the affected services.", "risk_and_exploitability": "The CVSS base score of 4.3 indicates a moderate risk, and the vulnerability is not listed in the CISA KEV catalog. EPSS data is unavailable, but the attack requires an authenticated session with a developer role and access to the project\u2019s API. Accordingly, the exploit is likely to be limited to users who already have legitimate access, but a malicious developer can misconfigure a protected environment, causing unintended deployments or environment mutilation. The vulnerability is therefore a medium\u2011risk concern that should be addressed promptly."}}}}, "created": "2026-04-09T08:16:11.568699+00:00", "updated": "2026-04-09T08:25:37.513913+00:00", "vendors": ["gitlab", "gitlab$PRODUCT$gitlab"]}
