{"schema":"threatline.record/2","record":{"id":"CVE-2026-29001","aliases":[],"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.","categories":["Unclassified"],"product":"TastyIgniter","vendor":"tastyigniter","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-29001","source_modified_at":"2026-10-23T13:28:37.642Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"TastyIgniter","vendor":"tastyigniter","versions":[{"status":"affected","version":"0","versionType":"semver","lessThanOrEqual":"4.4.5"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00644,"percentile":0.50252,"score_date":"2026-10-23"},"published_at":"2026-10-21T21:03:25.481Z","modified_at":"2026-10-23T13:28:37.642Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-29001","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T13:28:37.642Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-29001","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/tastyigniter/TastyIgniter/issues/1205#issuecomment-6314187869","tags":["technical-description","issue-tracking"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/tastyigniter-php-object-injection-via-settings-deserialization","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T13:28:37.642Z","content_hash":"57523867280b1209ed78e0dd2b8655f96e68ffd67dba8b6d205edcca0baaa25d"}}
