The Document Builder API improperly processes user-controlled converter XML supplied through the optional third argument of builder.SaveFile(). By injecting a duplicate m_sFileTo element, an attacker can override the server-generated output path and write arbitrary content outside the designated job directory. This allows the attacker to overwrite the runtime.json configuration file, modify the Document Builder executable path and arguments, and execute arbitrary commands when a subsequent Document Builder job is processed.","published":"2026-10-14T01:17:06.000Z","lastModified":"2026-10-16T19:56:00.000Z","status":"Awaiting Analysis","sourceIdentifier":"cve@mitre.org","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-73"],"affected":[],"epss":{"score":0.01042,"percentile":0.63907,"date":"2026-10-27","history":[{"date":"2026-10-14","score":0.01042,"percentile":0.63346}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.04%).
