CVE-2024-12848 is a missing authorization vulnerability (CWE-862) in the SKT Page Builder plugin for WordPress. The vulnerability arises because the 'addLibraryByArchive' function does not perform proper capability checks, allowing authenticated users with low privileges (subscriber-level and above) to upload arbitrary files. This can lead to remote code execution on the affected WordPress site. The issue affects all versions up to and including 4.6. The CVSS 3.1 base score is 8.8, indicating a high severity vulnerability with network attack vector, low attack complexity, and no user interaction required.

An attacker with subscriber-level access or higher can exploit this vulnerability to upload arbitrary files, which may lead to remote code execution. This compromises the confidentiality, integrity, and availability of the affected WordPress site. The vulnerability allows privilege escalation from low-privileged authenticated users to potentially full control over the web server environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict subscriber-level access and above to trusted users only. Monitor for plugin updates from sonalsinha21 and apply them promptly once released. Consider disabling or removing the SKT Page Builder plugin if it is not essential.
