CVE-2026-88891: Improper Privilege Management in Openpanel-dev openpanel
OpenPanel fails to enforce read-only project access level on 26 of 29 mutating procedures, allowing read-level members to modify, delete, and publish project data. Attackers with explicit read-only access can delete reports and dashboards, schedule entire projects for deletion, publish private analytics to public share links, and modify alerting rules by exploiting missing access level validation in mutation resolvers.
AI Analysis
Technical Summary
Openpanel-dev's openpanel suffers from improper privilege management due to failure to enforce read-only access restrictions on most mutating procedures. This allows attackers with explicit read-only access to escalate their privileges within the project by modifying, deleting, or publishing project data without authorization. The vulnerability affects 26 of 29 mutation resolvers that lack proper access level validation, enabling unauthorized data manipulation and exposure.
Potential Impact
Attackers with only read-level access can perform unauthorized destructive and publishing actions including deleting reports and dashboards, scheduling entire projects for deletion, publishing private analytics to public share links, and modifying alerting rules. This leads to data integrity loss, unauthorized data exposure, and potential disruption of project operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time.
