NCSC-2026-0367 [1.00] [H/H] Kwetsbaarheid verholpen in GitLab Community en Enterprise Editions

NCSC Security Advisories · 12 Sep 2026

GitLab heeft een kwetsbaarheid verholpen in GitLab Community en Enterprise Editions. De kwetsbaarheid bevindt zich in de repository commits API, waarbij een path traversal mogelijk is. Hierdoor kunnen niet-geauthenticeerde gebruikers willekeurige bestanden op het systeem lezen. De oorzaak ligt in onjuiste path confinement gecombineerd met ontbrekende authenticatiecontroles in de API-endpoint. CISA heeft CVE-2026-85706 opgenomen in de Known Exploited Vulnerabilities-catalogus en er is publieke exploitcode beschikbaar. Vooral internetbereikbare, zelfbeheerde GitLab-installaties lopen risico,...
