Description

The Seraphinite Accelerator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the seraph_accel_api AJAX action with fn=LogClear in all versions up to, and including, 2.28.14. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the plugin's debug/operational logs.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
