**Name of the Vulnerable Software and Affected Versions**
Shlink (affected versions not specified)
**Description**
An authenticated API key holder can perform a blind SQL injection by providing an unvalidated value in the `orderBy` query parameter of the tag statistics endpoint. This occurs because the input flows unsanitized into a Doctrine QueryBuilder ORDER BY clause, allowing the injection of arbitrary SQL fragments. This can lead to the extraction of sensitive data from any tenant, including long URLs, visitor records, IP addresses, geolocation data, user agents, and hashed API key secrets, using time-based, boolean-oracle, or error-based techniques.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
