CVE-2026-9843Network attack vector

Unauthenticated file deletion via bracket-parsed JSON key

Published Jun 20, 2026 · Updated Jun 20, 2026

Path traversal in view_page in CRM Perks Contact Form Entries 1.5.1 and earlier allows remote attackers to delete arbitrary server files. The function processes a traversal-bearing path hidden in a crafted form-entry JSON key after PHP bracket parsing bypasses its stored-path isset check. Deletion occurs only when an administrator views or edits the poisoned entry; removing wp-config.php can interrupt the site and enable code execution.
