CVE-2022-24898Public exploitNetwork attack vector

Arbitrary file read via external entity expansion

Published Apr 28, 2022 · Updated Apr 22, 2025

XXE in the XML script service in XWiki Commons allows remote authenticated users with Script rights to read server-accessible files. XMLUtils.parse leaves DOCTYPE declarations and external general and parameter entities enabled, so the parser resolves attacker-supplied file URIs into document content. Script rights are required, and disclosure is limited to files readable by the XWiki application-server account.
