Attackers can submit a serialized gadget chain, such as one generated via phpggc, through the admin settings form (for example the maintenance_message setting loaded by CheckMaintenance.php) to achieve arbitrary operating-system command execution as the PHP application process user, with the impact persisting until the value is overwritten.","severity":"high","score":8.6,"published":"2026-10-21T21:03:25.481Z","modified":"2026-10-28T01:58:42.698Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/tastyigniter/TastyIgniter/issues/1205#issuecomment-6314187869","https://www.vulncheck.com/advisories/tastyigniter-php-object-injection-via-settings-deserialization"],"sources":[{"name":"CVE","id":"CVE-2026-29001","modified":"2026-10-28T01:58:42.698Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-29001"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T23:45:31.121Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
