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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
