{"id":"CVE-2026-111628","summary":"10up Distributor before 2.3.2 PHP Object Injection via set_meta()","details":"10up Distributor before 2.3.2 contains a PHP object injection vulnerability that allows Contributor-level users to instantiate PHP objects by double unserializing distributed post meta. Attackers can store a serialized PHP string as meta, which set_meta() in includes/utils.php unserializes on the destination site, storing attacker-defined objects whose impact depends on loaded gadget classes.","aliases":["GHSA-wm53-9j85-ph6h"],"modified":"2026-10-21T02:56:23.434078265Z","published":"2026-10-16T17:39:02.847Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111628.json"},"references":[{"type":"PACKAGE","url":"https://github.com/10up/distributor"},{"type":"ARTICLE","url":"https://github.com/10up/distributor/blob/2.3.1/includes/utils.php#L192-L200"},{"type":"FIX","url":"https://github.com/10up/distributor/commit/7c57edb774d80534885ca6f2c46b95d333de6e5a"},{"type":"ADVISORY","url":"https://github.com/10up/distributor/releases/tag/2.3.2"},{"type":"ADVISORY","url":"https://github.com/10up/distributor/security/advisories/GHSA-wm53-9j85-ph6h"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111628.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111628"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/10up-distributor-before-2.3.2-php-object-injection-via-set-meta"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/10up/distributor","events":[{"introduced":"0"},{"fixed":"bcf821342f9bcce354815f24842402ca56e0b8e8"},{"fixed":"7c57edb774d80534885ca6f2c46b95d333de6e5a"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"2.3.2"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"range":[{"fixed":"7c57edb774d80534885ca6f2c46b95d333de6e5a"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"2.3.2","range":[{"fixed":"bcf821342f9bcce354815f24842402ca56e0b8e8"}]}]}}],"versions":["2.3.1","2.3.0","2.2.0","2.1.0","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","2.0.0-rc1","2.0.0-beta2","2.0.0-beta1","1.9.1","1.9.0","1.8.0","1.7.1","1.7.0","1.6.9","1.6.8","1.6.7","1.6.6","1.6.5","1.6.4","1.6.3","1.6.2","1.6.1","1.6.0","1.5.0","1.4.1","1.4.0","1.3.9","1.3.8","1.3.7","1.3.6","1.3.5","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.3","1.2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111628.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
