CVE-2026-5337
Recycled NVD feed posts; no PoC, no KEV, no urgent patching signal yet.
What: Insecure Direct Object Reference (IDOR) in Frontend File Manager Plugin WordPress through v23.6 allows authenticated Subscriber-level users to access files belonging to other users by tampering with the file_id parameter.
Why it matters: WordPress plugin affecting file access control; affects authenticated users with low privileges escalating to read admin/sensitive files. No KEV listing, no CVSS/EPSS scores, and no public PoC or in-the-wild reports evident in chatter.
Where it's seen: Feed aggregators (CVE trackers, Vulmon) republishing NVD description same-day; no vendor advisory, researcher PoC, or defender triage signals detected.
RISK: MODERATE — Affects WordPress sites; requires authentication; file disclosure only, not RCE.

Description
During the analysis, it was identified that authenticated attackers with Subscriber-level access or higher are able to perform an Insecure Direct Object Reference (IDOR) attack. This vulnerability exists because the Frontend File Manager Plugin WordPress plugin through 23.6 does not properly validate user authorization for the requested uploaded file when processing download requests. By modifying the value of the 'file_id' parameter in the download endpoint (e.g., http://localhost/?do=wpfm_download&file_id=40&nm_file_nonce=a36fb893f1), an attacker can access files belonging to other users, including privileged users such as administrators. This allows unauthorized access/read to sensitive data stored within the application.
