{"id":"CVE-2026-37552","details":"Unsafe deserialization vulnerability in MixPHP Framework 2.x thru 2.2.17. The sync-invoke TCP server (Server.php:87) receives data from a TCP socket, passes it directly to Opis\\Closure\\unserialize(), then executes the result via call_user_func(). No authentication or signature verification exists on the TCP connection. An attacker with access to the localhost TCP port (server binds 127.0.0.1) can send a crafted serialized PHP closure to achieve arbitrary code execution.","modified":"2026-07-15T01:49:13.888562695Z","published":"2026-05-01T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37552.json"},"references":[{"type":"WEB","url":"https://gist.github.com/sgInnora/fa46386840fe978a30d7e53c458f2975"},{"type":"WEB","url":"https://github.com/mix-php/mix/blob/v2.2.17/src/sync-invoke/src/Server.php"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37552.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-37552"},{"type":"PACKAGE","url":"https://github.com/mix-php/mix"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mix-php/mix","events":[{"introduced":"e91036a4b8a74001c4909ec2e7f4dd15e23b95aa"},{"last_affected":"8b002644d46cddf1fc4f42bf134e46620e1a6450"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:openmix:mix_php:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.0.1"},{"last_affected":"2.2.17"}]}}],"versions":["v2.2.17","v2.2.16","v2.2.15","v2.2.14","v2.2.13","v2.2.12","v2.2.11","v2.2.9","v2.2.7","v2.2.5","v2.2.4","v2.1.15","v2.1.12","v2.1.11","v2.1.10","v2.1.9","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.1","v2.1.0","v2.1.0-RC2","v2.1.0-RC","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-37552.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AC:L/AV:L/A:H/C:H/I:H/PR:N/S:U/UI:N"}]}
