Authenticated data disclosure via external entity resolution
Published May 4, 2026 · Updated May 4, 2026
XXE in ILM Informatique jOpenDocument 1.5 allows remote authenticated users to disclose data through crafted OpenDocument files. The XML parser resolves an external entity URI from untrusted document XML, but the record does not disclose the parser entry point or affected XML part. Exploitation requires low-privileged network access to an application that passes attacker-controlled documents to the library; the exposed data is unspecified.
