Deeper analysis
The SKT Page Builder plugin for WordPress is vulnerable to arbitrary file uploads because the addLibraryByArchive function lacks a capability check in all versions through 4.6. This flaw is tracked as CVE-2024-12848 and carries a CVSS 3.1 score of 8.8 under CWE-862.
Authenticated attackers who possess at least subscriber-level access can invoke the affected function to upload arbitrary files, resulting in remote code execution on the server. The attack requires no user interaction and can be performed over the network.
Public references, including Wordfence advisory data and WordPress plugin trac changesets, document the availability of patched versions that address the missing authorization check. The EPSS score has remained near 0.08 with only minor fluctuation between its recorded peak and current value.
