Prior to versions 6.8.150, 25.0.82, and 26.0.5, there is a remote code execution (RCE) vulnerability in Group-Office. The endpoint email/message/tnefAttachmentFromTempFile directly concatenates the user-controlled parameter tmp_file into an exec() call. By injecting shell metacharacters into tmp_file, an authenticated attacker can execute arbitrary system commands on the server. This issue has been patched in versions 6.8.150, 25.0.82, and 26.0.5.","published":"2026-02-04T21:16:02.000Z","lastModified":"2026-06-17T10:24:46.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":9.4,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-78"],"affected":["group-office/group office"],"epss":{"score":0.20135,"percentile":0.97451,"date":"2026-10-30","history":[{"date":"2026-09-24","score":0.03489,"percentile":0.88674},{"date":"2026-10-25","score":0.20135,"percentile":0.97434}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 20.1%, higher than 97% of all known CVEs.
