CVE-2026-9204

Status: AnalyzedMedium (6.5)—

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.10 before 18.10.8, 18.11 before 18.11.5, and 19.0 before 19.0.2 that under certain conditions could have allowed an authenticated user to read arbitrary files from the Gitaly server and access internal network resources during repository import, due to insufficient validation of secondary URLs.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
