Link Library <= 7.9.2 – Unauthenticated SQL Injection

Sources read

Source agreement

Tam uyum

Evidence confidence

%63

Short explanation

The Link Library plugin versions up to and including 7.9.2 are vulnerable to time‑based SQL injection via the 'link_url' parameter. Unauthenticated attackers can extract sensitive database information. The CVSS base score is 7.5 (High). Patch status is not confirmed in official sources.

Why does it matter?

An unauthenticated flaw enables attackers to directly steal data and compromise application integrity.

What should be done?

Follow the vendor advisory and upgrade to the latest version
Restrict incoming requests to the 'link_url' parameter via firewall rules
Monitor for abnormal query latency to detect exploitation attempts

Show the technical text from the sources

The Link Library plugin for WordPress is vulnerable to time-based SQL Injection via the 'link_url' parameter in all versions up to, and including, 7.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
