CVE-2026-80518
LowCVSS 3.7Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
The WP Ultimate CSV Importer WordPress plugin before 9.2 does not use a site-specific secret when deriving the storage location of the import logs it writes under the uploads directory, nor does it block direct access to them, allowing unauthenticated attackers to retrieve the personal data of users imported from a CSV file.
Risk Assessment
Personal data of imported users may leak to unauthorized parties, risking data protection violations and breach notification obligations. The risk is high because the attack requires no authentication.
Recommendation
Update the WP Ultimate CSV Importer plugin to version 9.2 or later. Additionally, consider removing old import logs from the uploads directory and restricting access to it.
