{"id":"CVE-2023-4423","summary":"WP Event Manager – Events Calendar, Registrations, Sell Tickets with WooCommerce \u003c= 3.1.37.1 - Authenticated (Admin+) Stored Cross-Site Scripting","details":"The WP Event Manager – Events Calendar, Registrations, Sell Tickets with WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 3.1.37.1  due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","modified":"2026-08-12T03:51:36.980973097Z","published":"2023-09-27T03:03:01.373Z","database_specific":{"cna_assigner":"Wordfence","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/4xxx/CVE-2023-4423.json"},"references":[{"type":"WEB","url":"https://github.com/Jacky-Y/vuls/blob/main/vul5.md"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=2969034%40wp-event-manager%2Ftrunk&old=2953169%40wp-event-manager%2Ftrunk&sfp_email=&sfph_mail="},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/dd9d22b0-a84a-4bf2-b8b4-89bae2970f29?source=cve"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/4xxx/CVE-2023-4423.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-4423"},{"type":"REPORT","url":"https://github.com/wpeventmanager/wp-event-manager/issues/1483"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wpeventmanager/wp-event-manager","events":[{"introduced":"0"},{"fixed":"cda76d7cf6952390755edd40994885bcbb16ca4a"}],"database_specific":{"cpe":"cpe:2.3:a:wp-eventmanager:wp_event_manager:*:*:*:*:*:wordpress:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"3.1.37.1"},{"fixed":"3.1.38"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["3.1.37.1","3.1.37","3.1.33","3.1.32","3.1.31","3.1.30","3.1.29","3.1.28","3.1.27","3.1.26","3.1.25","3.1.24","3.1.23","3.1.21","3.1.20","3.1.19","3.1.18","3.1.17","3.1.16","3.1.15","3.1.14"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-4423.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N"}]}
