Unauthenticated data compromise via external XML entities
Published Aug 10, 2026 · Updated Aug 10, 2026
XXE in Jaspersoft JasperReports Server 9.0.0 before HF-9 and 10.0.0 before HF-10 allows remote attackers to compromise server data. Jaspersoft has not published the affected XML-processing endpoint or the parser operation that resolves attacker-controlled external entities. No authentication or user interaction is required; the published assessment identifies effects on server data and service availability without describing concrete post-exploitation actions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0.0 <HF-10
- Affected versionversion=9.0.0 <HF-9
