The above mentioned extensions are insecure by default, allowing external entities to be specified by adding a specific DOCTYPE element to XML documents and strings. By exploiting this vulnerability an application may be coerced to open arbitrary files and/or TCP connections.\n- XML Entity Expansion (XEE) vectors, leading to Denial of Service vectors. XEE attacks occur when the XML DOCTYPE declaration includes XML entity definitions that contain either recursive or circular references; this leads to CPU and memory consumption, making Denial of Service exploits trivial to implement.\n","severity":"critical","score":9.8,"published":"2024-06-07T21:16:36.000Z","modified":"2024-12-04T05:32:07.571Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zendframework1","sources":[{"name":"OSV · GHSA-mhpx-3rv8-wrjm","url":"https://osv.dev/vulnerability/GHSA-mhpx-3rv8-wrjm"}],"ranges":[{"events":[{"introduced":"1.12.0"},{"fixed":"1.12.4"}],"type":"ECOSYSTEM"}],"versions":["1.12.0","1.12.1","1.12.2","1.12.3"],"fixed":["1.12.4"]}],"sourceAffected":[],"references":["https://framework.zend.com/security/advisory/ZF2014-01","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework1/ZF2014-01.yaml","https://github.com/zendframework/zf1"],"sources":[{"name":"OSV","id":"GHSA-mhpx-3rv8-wrjm","modified":"2024-12-04T05:32:07.571126Z","url":"https://osv.dev/vulnerability/GHSA-mhpx-3rv8-wrjm"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8}],"products":[],"remediation":[],"kev":{"status":"unavailable","checkedAt":"2026-10-28T19:30:46.166Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
