This flaw allows users with the Subscriber role to modify site-wide presentation settings and delete imported site-builder content.
AI Analysis
Technical Summary
The Solace Extra WordPress plugin prior to version 1.6.1 does not enforce capability checks on multiple AJAX endpoints and exposes the nonce token on admin pages accessible by users with minimal privileges. This improper access control (CWE-284) enables low-privileged users, such as Subscribers, to perform unauthorized modifications including altering site-wide presentation settings and deleting imported site-builder content. No CVSS score or vendor advisory is currently available, and no patch or official remediation guidance has been provided yet.
Potential Impact
Users with the Subscriber role, typically having very limited permissions, can exploit this vulnerability to modify critical site-wide settings and delete content imported by site builders. This could lead to unauthorized changes in website appearance and potential data loss or disruption of site functionality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Subscriber role capabilities where possible and monitor for suspicious activity related to site-wide settings and content deletion.
