What is CVE-2026-80518?

The WP Ultimate CSV Importer plugin for WordPress, prior to version 9.2, presents a security risk by failing to implement a site-specific secret to manage the storage of import logs. This oversight allows unauthenticated attackers to access sensitive user data stored in these logs, which are located in the uploads directory. The lack of restrictions on file access may lead to unauthorized data exposure, highlighting a need for stringent access control measures.

Affected Version(s)

WP Ultimate CSV Importer 0 < 9.2

Exploit Proof of Concept (PoC)
