CVE-2026-69101: Improper Restriction of XML External Entity Reference in datavane tis
Datavane TIS v5.0.0 contains an XML external entity (XXE) injection vulnerability that allows authenticated attackers to perform server-side request forgery and out-of-band file exfiltration by supplying a crafted taskScript payload to the doEditWorkflow endpoint, which processes XML through an unhardened DocumentBuilderFactory with external entities and DTD loading enabled. 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.
AI Analysis
Technical Summary
CVE-2026-69101 is an XXE injection vulnerability in Datavane TIS up to version 5.0.0. The vulnerability arises because the doEditWorkflow endpoint uses an unhardened DocumentBuilderFactory that permits external entity and DTD processing. An authenticated attacker can supply a malicious XML payload referencing an external DTD, causing the server to make outbound HTTP requests to attacker-controlled infrastructure and leak local files such as configuration files and Derby database credentials.
Potential Impact
Successful exploitation allows an authenticated attacker to perform server-side request forgery and out-of-band file exfiltration. This can lead to disclosure of sensitive local files readable by the TIS process user, including configuration and database credential files, potentially compromising the confidentiality and integrity of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the doEditWorkflow endpoint to trusted users only and monitor for suspicious outbound requests. Avoid processing untrusted XML with external entity and DTD loading enabled.
