OPENKM COMMUNITY EDITION · CVE-2026-112181 · Other
FIX → 7.0.4 · 6.3.14 (pending release)
OpenKM Community Edition 6.3.3 through 6.3.13 and 7.0.3 resolve external XML entities in FormUtils / LocalEntityResolver. An authenticated user with ROLE_USER can send a REST request that makes the server fetch attacker-chosen resources. On 6.3.x INCIBE describes this as SSRF. On 7.0.3 it also allows reading local files and reaching internal HTTP services.

Self-hosted OpenKM Community Edition servers on 6.3.3 through 6.3.13 or 7.0.3 where anyone holds a ROLE_USER account (including ordinary staff or guest accounts). The attacker must be logged in; no admin rights are needed. Servers already on 7.0.4 can skip it. Other branches are not named by INCIBE. The vendor's proxy block on /OpenKM/services/rest/workflow/* and /OpenKM/services/OKMWorkflow is listed for the sibling workflow issue (CVE-2026-112182), and INCIBE does not say it covers this one.
Not affected if no-user-accounts, openkm-7.0.4-or-later, other-versions

6.3.3 through 6.3.13 or 7.0.3 and any account has ROLE_USER. 7.0.4 contains the fixVulnerability 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.
