A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
Probability of exploitation in the next 30 days: 73.7% (FIRST EPSS); higher than 99.4% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Unknown WP Fastest Cache 1.2.2.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to Unknown WP Fastest Cache 1.2.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The WP Fastest Cache WordPress plugin before 1.2.2 does not properly sanitise and escape a parameter before using it in a SQL statement, leading to a SQL injection exploitable by unauthenticated users.
