This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the plugin's Guest Submissions setting (allow_submission_by_anonymous_user) to be enabled, which allows unauthenticated attackers to submit event types via the frontend form; when that setting is disabled, exploitation requires at minimum a subscriber-level authenticated account."}], "title": "EventPrime <= 4.3.4.2 - Unauthenticated Stored Cross-Site Scripting via 'new_event_type_background_color' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/2abd400b-c633-4b38-ad3e-c9ce602ff07f?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/tags/4.3.4.2/admin/class-eventprime-event-calendar-management-admin.php#L1973"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/tags/4.3.4.2/includes/class-ep-ajax.php#L1200"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/tags/4.3.4.2/includes/class-eventprime-functions.php#L9793"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/trunk/admin/class-eventprime-event-calendar-management-admin.php#L1973"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/trunk/includes/class-ep-ajax.php#L1200"}, {"url": "https://plugins.trac.wordpress.org/browser/eventprime-event-calendar-management/trunk/includes/class-eventprime-functions.php#L9793"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3595157%40eventprime-event-calendar-management&new=3595157%40eventprime-event-calendar-management"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N", "baseScore": 7.2, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "Philipp Doblhofer"}], "timeline": [{"time": "2026-06-26T16:40:56.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-08T00:00:00.000Z", "lang": "en", "value": "Disclosed"}]}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2026-07-09T12:19:01.218748Z", "id": "CVE-2026-13441", "options": [{"Exploitation": "none"}, {"Automatable": "yes"}, {"Technical Impact": "partial"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-09T12:19:37.188Z"}}]}}
