{"id":"CVE-2025-43960","aliases":["GHSA-mqh4-2mm8-g7w9"],"url":"https://o3.security/vulnerability/CVE-2025-43960","summary":"Adminer PHP Object Injection issue leads to Denial of Service","details":"Adminer 4.8.1, when using Monolog for logging, allows a Denial of Service (memory consumption) via a crafted serialized payload (e.g., using s:1000000000), leading to a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering Adminer’s interface unresponsive and causing a server-level DoS. While the server may recover after several minutes, multiple simultaneous requests can cause a complete crash requiring manual intervention.","published":"2025-08-25T00:00:00Z","modified":"2026-08-12T03:51:19.620481411Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"vrana/adminer","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/vrana/adminer/compare/v4.8.1...v4.8.2"},{"type":"WEB","url":"https://www.adminer.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/43xxx/CVE-2025-43960.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-43960"},{"type":"PACKAGE","url":"https://github.com/Seldaek/monolog"},{"type":"PACKAGE","url":"https://github.com/far00t01/CVE-2025-43960"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:19.620481411Z"}}
