{"id":"CVE-2026-87115","published":"2026-10-03T07:16:48.347","lastModified":"2026-10-06T15:04:52.637","description":"The VikAppointments Services Booking Calendar plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the extract function in all versions up to, and including, 1.2.21. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation requires at least one File-type custom field to be published on the confirmation page shortcode, as this field is not created by default during plugin installation.","cvssScore":9.1,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/controllers/confirmapp.php#L88","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/helpers/libraries/customfields/types/file.php#L131","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/site/helpers/libraries/customfields/types/file.php#L53","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.19/vikappointments.php#L237","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.21/site/controllers/confirmapp.php#L88","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.21/site/helpers/libraries/customfields/types/file.php#L131","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.21/site/helpers/libraries/customfields/types/file.php#L53","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikappointments/tags/1.2.21/vikappointments.php#L237","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3721264%40vikappointments&new=3721264%40vikappointments","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/75fc5df5-a774-4fe1-8452-d35ba7b69081?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows unauthenticated attackers to delete arbitrary files, potentially leading to remote code execution.","exploitability":"Exploitation requires at least one File-type custom field on the confirmation page shortcode, making it moderately difficult.","blast_radius":"If exploited, the impact could be severe, as it could lead to remote code execution on the server.","remediation":"Disable the affected feature or upgrade to version 1.2.22 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","file-deletion","wordpress","unauthenticated"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-03T08:46:25.270Z"}}
