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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","score":8.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-611"],"references":["https://github.com/datavane/tis","https://github.com/datavane/tis/commit/2a84a1b84218a303e3e0a4823023363d5a7abfa1","https://github.com/datavane/tis/issues/496","https://www.vulncheck.com/advisories/datavane-tis-xxe-injection-via-doeditworkflow-endpoint","https://github.com/datavane/tis/issues/496"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-69101","score":0.00432,"percentile":0.37522,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
