{"id":"CVE-2026-29001","summary":"TastyIgniter 4.4.5 PHP Object Injection via Settings Deserialization","details":"TastyIgniter through 4.4.5 contain a PHP object injection vulnerability that allows authenticated administrators to achieve arbitrary code execution by submitting a serialized PHP object as a settings value, which is stored unsanitized and later unserialized by getValueAttribute() when the setting is read. 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.","modified":"2026-10-22T10:46:01.762701243Z","published":"2026-10-21T21:03:25.481Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29001.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29001.json"},{"type":"PACKAGE","url":"https://github.com/tastyigniter/TastyIgniter"},{"type":"ARTICLE","url":"https://github.com/tastyigniter/TastyIgniter/issues/1205#issuecomment-6314187869"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29001"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/tastyigniter-php-object-injection-via-settings-deserialization"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tastyigniter/tastyigniter","events":[{"introduced":"0"},{"last_affected":"7757e3c8f2fa12bdc53effba19cc5540857e4022"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"4.4.5"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["v4.4.5","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.4","v4.3.3","v4.3.2","v4.3.1","v4.2.5","v4.2.2","v4.2.1","v4.2.0","v4.0.2","v4.0.1","v3.7.7","v3.7.6","v3.7.5","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.6","v3.6.4","v3.6.3","v3.6.0","v3.5.5","v3.5.4","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.1","v3.4.0","v3.3.2","v3.3.1","v3.3.0","v3.2.2","v3.2.1","v3.2.0","v3.1.2","v3.1.1","v3.1.0","v3.1.0-rc.1","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.4-beta.28","v3.0.4-beta.27","v3.0.4-beta.26","v3.0.4-beta.25.2","v3.0.4-beta.25","v3.0.4-beta.24.4","v3.0.4-beta.24.3","v3.0.4-beta.24.2","v3.0.4-beta.24.1","v3.0.4-beta.24","v3.0.4-beta.23.2","v3.0.4-beta.23.1","v3.0.4-beta.23","v3.0.4-beta.22.4","v3.0.4-beta.22.3","v3.0.4-beta.22.2","v3.0.4-beta.22.1","v3.0.4-beta.22","v3.0.4-beta.21","v3.0.4-beta.20.1","v3.0.4-beta.20","v3.0.4-beta.19","v3.0.4-beta.18","v3.0.4-beta.17","v3.0.4-beta.16","v3.0.4-beta.15","v3.0.4-beta.14","v3.0.4-beta.13","v3.0.4-beta.12","v3.0.4-beta.11","v3.0.4-beta.10","v3.0.4-beta.9.1","v3.0.4-beta.9","v3.0.4-beta.8","v3.0.4-beta.7","v3.0.4-beta.6","v3.0.4-beta.5","v3.0.4-beta.4","v3.0.4-beta.3","v3.0.4-beta.2","v3.0.4-beta","2.1.1","2.1.0","2.0.0","v1.4.2-beta","v1.4.1.0-beta","v1.4.1-beta","v1.4.0-beta","v1.3-beta","v1.2.1-beta","v1.2-beta","v1.1-beta","v1.0-beta"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29001.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
