Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-200.
Summary
The WP Remote Users Sync WordPress plugin before 2.2.0 does not adequately restrict access to the user export files it writes beneath the public web root. It relies on an Apache access-control file that other web servers such as Nginx ignore. An unauthenticated attacker who requests the export's predictable file name while the file is present can retrieve the exported users' personal data. The CNA rated it CVSS 3.1 3.7 (LOW), and CISA has not added it to KEV.
