{"id":"CVE-2025-43960","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.","aliases":["GHSA-mqh4-2mm8-g7w9"],"modified":"2026-08-12T03:51:19.620481411Z","published":"2025-08-25T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/43xxx/CVE-2025-43960.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vrana/adminer","events":[{"introduced":"1f173e18bdf0be29182e0d67989df56eadea4754"},{"last_affected":"1f173e18bdf0be29182e0d67989df56eadea4754"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:adminer:adminer:4.8.1:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.8.1"},{"last_affected":"4.8.1"}]}}],"versions":["4.8.1","v4.8.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-43960.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"}]}
