## Description

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.
