CVE-2022-25312Network attack vector

File disclosure via unrestricted external entity resolution

Published Mar 4, 2022 · Updated Aug 3, 2024

XXE injection in Apache Any23 before 2.7 allows remote attackers to read local files or make backend requests through RDFa extraction. The XSLTStylesheet extractor accepts external entity URIs during XML processing instead of restricting their resolution. No authentication or user interaction is required when an exposed application passes untrusted RDFa/XML to the extractor; access remains bounded by the process file and network permissions.
