What is known

The Short URL WordPress plugin through 1.6.8 does not properly sanitise and escape a parameter before using it in SQL statement, leading to a SQL injection exploitable by users with relatively low privilege on the site, like subscribers.

Business impact

Successful exploitation of CVE-2023-2921, a high vulnerability (CVSS 8.8) affecting short url, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether short url is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
