Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-13333 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Advancedfilemanager Advanced File Manager. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 41% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Advanced File Manager plugin for WordPress contains an arbitrary file upload vulnerability (CVE-2024-13333) in versions 5.2.12 through 5.2.13. The flaw stems from missing file type validation inside the fma_local_file_system function, which permits upload of arbitrary files when the “Display .htaccess?” option is enabled. The issue is tracked under CWE-434 and carries a CVSS 3.1 score of 7.5.
Authenticated attackers holding subscriber-level access or higher can exploit the weakness if an administrator has explicitly granted them upload rights. Successful exploitation allows the attacker to place malicious files on the server, which may then be executed to achieve remote code execution.
Public references include the plugin’s Trac repository showing the vulnerable code path and a subsequent changeset (3222740) that addresses the validation gap, along with a detailed Wordfence advisory. The associated EPSS score has remained flat at 0.1782 with no material increase since disclosure.

Vulnerability Data
The Advanced File Manager plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'fma_local_file_system' function in versions 5.2.12 to 5.2.13. This makes it possible for authenticated attackers, with Subscriber-level access and above…

and upload permissions granted by an administrator, to upload arbitrary files on the affected site's server which may make remote code execution possible. The function can be exploited only if the "Display .htaccess?" setting is enabled.

Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Hardened configuration baselines can enforce allowed file types and processing rules.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Secure development practices include input validation and file-type restrictions that prevent this weakness.
