Summary

CVE-2023-6063 is a high-severity SQL Injection (CWE-89) vulnerability in Wpfastestcache Wp Fastest Cache. Its CVSS base score is 7.5 (High).

Operationally, ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

The vulnerability CVE-2023-6063 is an unauthenticated SQL injection flaw present in the WP Fastest Cache WordPress plugin prior to version 1.2.2. It arises because the plugin fails to properly sanitize and escape a parameter before incorporating it into a SQL statement, corresponding to CWE-89 and carrying a CVSS 3.1 score of 7.5 that reflects high confidentiality impact over a network vector with no required privileges or user interaction.

An attacker with no authentication can supply a crafted parameter to the affected plugin endpoint, enabling direct execution of arbitrary SQL queries against the underlying database and potential extraction of sensitive data such as user credentials or site configuration.

Public advisories published by WPScan state that the flaw was resolved in plugin release 1.2.2 and explicitly advise site administrators to update immediately to eliminate the injection vector.

The associated EPSS reaches a current value of 0.9137 with a recorded peak of 0.9221, indicating sustained and elevated exploitation interest following disclosure.
