Attackers can send a malicious XML document containing an external DTD reference to the edit_workflow action, causing the server to issue outbound HTTP requests to attacker-controlled infrastructure and exfiltrate local files readable by the TIS process user, including configuration files and Derby database credentials.","published":"2026-08-14T15:17:10.053","modified":"2026-08-14T15:17:10.053","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/datavane/tis/commit/2a84a1b84218a303e3e0a4823023363d5a7abfa1","label":"datavane/tis@2a84a1b"},"references":[{"type":"WEB","url":"https://github.com/datavane/tis"},{"type":"WEB","url":"https://github.com/datavane/tis/commit/2a84a1b84218a303e3e0a4823023363d5a7abfa1"},{"type":"WEB","url":"https://github.com/datavane/tis/issues/496"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/datavane-tis-xxe-injection-via-doeditworkflow-endpoint"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T15:17:10.053"}}
