EUVD-2026-125270
Severity: HIGH
Base Score: 8.3
CVSS Version: 4.0
Vulnerability Description
Vulnerability due to inadequate restriction of references to external XML entities in OpenKM Community Edition. The XML processing in FormUtils / LocalEntityResolver does not properly restrict the resolution of external resources. An authenticated remote attacker with the ROLE_USER role can exploit the flaw via a REST request. In the 6.3.x branch, this allows the attacker to trigger HTTP requests under their control (SSRF); in 7.0.3, it allows the attacker to read local files and access internal HTTP resources from the server.
