Specific Flaws Uncovered in King Addons
Arbitrary File Upload Flaw (CVE-2025-6327)
A severe vulnerability in King Addons, identified as CVE-2025-6327, involves an exposed AJAX handler nonce that permits unauthenticated users to upload files to a site. This flaw bypasses critical security checks, enabling attackers to place potentially malicious content in web-accessible directories such as wp-content/uploads/king-addons/forms/. The ease of exploitation makes this issue particularly alarming for site administrators unaware of the risk.
Further compounding the problem is the inadequate validation within the file_validity() method, which fails to scrutinize file types effectively. Attackers can manipulate parameters to upload harmful scripts or executables, posing a direct threat of site compromise. This vulnerability exemplifies how seemingly minor oversights in code can open significant backdoors for exploitation.
The implications of such a flaw are far-reaching, as uploaded malicious files could facilitate further attacks, including data theft or site defacement.
