SCA: security update for org.xwiki.platform:xwiki-platform-oldcore (GHSA-qj4x-9g63-25g6)

high Tenable Cloud Security Plugin ID 444475

Description

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

 - XWiki Platform is a generic wiki platform. Prior to 17.10.5 and 18.2.0, the /skin/ action in
 com.xpn.xwiki.web.SkinAction can resolve double-encoded parent-directory segments outside the intended
 skin or web-application resource prefix when Jetty 12 or later decodes the request path. The affected
 lookup is replaced with Environment.getResourceAsStream(String, String), which constrains a resource to
 its expected prefix. An unauthenticated remote attacker can use the vulnerable behavior to read arbitrary
 resources permitted to the Jetty process, including WEB-INF/xwiki.cfg and, depending on deployment depth
 and operating-system permissions, host files. Tomcat and Jetty versions before 12 do not appear affected.
 This issue is fixed in versions 17.10.5 and 18.2.0. (CVE-2026-34151)

Solution

Update the org.xwiki.platform:xwiki-platform-oldcore library and its related packages to version 17.10.5 or later.
