CVE-2023-3077

A public proof of concept exists; no exploitation attested.

  • Published2023-07-10
  • Fixed in3.9.8

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The MStore API WordPress plugin before 3.9.8 does not sanitise and escape a parameter before using it in a SQL statement, leading to a Blind SQL injection exploitable by unauthenticated users. This is only exploitable if the site owner elected to pay to get access to the plugins' pro features, and uses the woocommerce-appointments plugin.
