This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.","provenance":"source","from":"CVE.org"},"cvss":{"score":9.8,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00609,"percentile":0.4915,"provenance":"source"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7a116f28-a560-4b54-9cd1-f1dd9ac3238d?source=cve","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/contact-form-entries/trunk/contact-form-entries.php#L3016","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/contact-form-entries/trunk/contact-form-entries.php#L2972","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3474882/","tags":[]}],"priority":{"score":16.7,"factors":[{"name":"EPSS percentile","points":9.83},{"name":"CVSS severity","points":6.86}]},"vendorSlug":"crmperks","affectedVersions":[{"vendor":"crmperks","product":"Database for Contact Form 7, WPforms, Elementor forms","versions":["<= 1.4.7"]}],"euvd":{"id":"EUVD-2026-9818","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-crmperks-database-for-contact-form-7-wpf-cve-2025-7384","children":[{"from":"CVE-2026-2599","to":"CVE-2026-12081","relation":"incomplete-fix","confidence":"high","kind":"lineage","evidence":[{"kind":"text","provenance":"source","relation":"incomplete-fix","quote":"This is an incomplete fix of CVE-2025-7384 and CVE-2026-2599, whose deserialization paths were hardened while the entry-editor file-field path was missed.","from":"CVE.org","in":"CVE-2026-12081"}]}]}}
