Summary

CVE-2024-6313 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 3.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

The Gutenberg Forms plugin for WordPress, in versions up to and including 2.2.9, contains an arbitrary file upload vulnerability (CWE-434) in the upload handling logic. The affected code in Bucket.php and email.php allows users to specify permitted file types without sufficient server-side validation or restriction, enabling uploads of any file to the site server.

Unauthenticated attackers can exploit the flaw over the network by submitting crafted form uploads that bypass the type checks. Successful exploitation grants the ability to place arbitrary files, including web shells, on the target server and achieve remote code execution with full confidentiality, integrity, and availability impact, as reflected in the CVSS 9.8 score.

EPSS for the CVE rose from a low baseline to a peak of 0.2971 on 2025-12-11 before receding to the current value of 0.2319, indicating measurable post-disclosure exploitation interest. The referenced advisories and code traces from Wordfence and the WordPress plugin repository highlight the vulnerable functions but do not detail a specific patched version or mitigation steps beyond the need to address the upload controls.
