Attackers can pass malicious serialized data through the billing_data POST field to the unserialize() function without allowed_classes restrictions, enabling exploitation of available POP chains to achieve remote code execution as root.","published":"2026-09-22T18:17:15.000Z","lastModified":"2026-09-26T00:16:35.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":9.2,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/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-502"],"affected":[],"epss":{"score":0.0096,"percentile":0.61352,"date":"2026-10-27","history":[{"date":"2026-09-23","score":0.0096,"percentile":0.60062}]},"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 (0.96%).
