{"id":"GHSA-mqh4-2mm8-g7w9","aliases":["CVE-2025-43960"],"title":"Adminer PHP Object Injection issue leads to Denial of Service","description":"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.","severity":"high","score":8.6,"published":"2025-08-25T15:32:00.000Z","modified":"2025-08-25T22:59:48.749Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"vrana/adminer","ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.8.1"}],"type":"ECOSYSTEM"}],"versions":["v4.2.0","v4.2.1","v4.2.2","v4.2.3","v4.2.4","v4.2.5","v4.3.0","v4.3.1","v4.4.0","v4.5.0","v4.6.0","v4.6.1","v4.6.2","v4.6.3","v4.7.0","v4.7.1","v4.7.2","v4.7.3","v4.7.4","v4.7.5","v4.7.6","v4.7.7","v4.7.8","v4.7.9","v4.8.0","v4.8.1"],"fixed":[]}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2025-43960","https://github.com/far00t01/CVE-2025-43960","https://github.com/vrana/adminer"],"sources":[{"name":"OSV","id":"GHSA-mqh4-2mm8-g7w9","modified":"2025-08-25T22:59:48.749614Z","url":"https://osv.dev/vulnerability/GHSA-mqh4-2mm8-g7w9"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","score":8.6}]}
