# OpenKM Community: XML entity handling lets logged-in users read server files

Link for people: https://infrastack.ai/live/CVE-2026-112181 (this .md is for agents)

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.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:OpenKM Community Edition affected 6.3.3 through 6.3.13, and 7.0.3 fixed 7.0.4, 6.3.14 (pending release)

## How to check

Find your OpenKM Community Edition version (Administration > About, or the login page footer). Exposed if it is 6.3.3 through 6.3.13 or 7.0.3 and any account has ROLE_USER. 7.0.4 contains the fix. Also review who can create accounts.

## Fix

On 7.0.3 update to OpenKM CE 7.0.4 (released). On 6.3.3 through 6.3.13 the fix is planned for 6.3.14, which is not released yet; INCIBE relays the vendor's advice to migrate to 7.0.4, and 7.x has no jBPM workflow engine.

No exploitation or PoC noted; the temporary workflow block applies to CVE-2026-112182, not recorded as mitigation here. The default reachability of the endpoint was not stated. Sibling: CVE-2026-112182.

## From the sources

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.
