SCA: security update for org.geonetwork-opensource:gn-web-app (GHSA-5hx7-j24v-rffj)

high Tenable Cloud Security Plugin ID 447865

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- GeoNetwork is a catalog application to manage spatially referenced resources. Prior to 4.2.17 and 4.4.12,
POST /api/tools/ogc/sld accepted a caller-supplied WMS server URL and performed a server-side HTTP GET
without destination validation. An anonymous attacker could make the GeoNetwork server send requests to
internal hosts that are not publicly reachable. When the outbound response was XML, the endpoint could
store and return the fetched body, making the request forgery non-blind and enabling internal data
disclosure, authorization bypass, and network reconnaissance. This issue is fixed in versions 4.2.17 and
4.4.12. (CVE-2026-55864)

Solution

Update the org.geonetwork-opensource:gn-web-app library and its related packages to version 4.2.17 or later.
