CVE-2026-39053Network attack vector

File disclosure and SSRF via unsafe XML parsing

Published May 15, 2026 · Updated May 15, 2026

XXE in Oinone Pamirs 7.0.0 allows remote attackers to read local files or issue server-side requests through crafted XML. PamirsXmlUtils.fromXML(...) and ViewXmlUtils.fromXML(...) pass attacker-controlled XML into XStream without restricting external entity resolution. No authentication or user interaction is required when an exposed framework parsing entry point accepts the XML; disclosed impacts are file reads and SSRF.
