Name of the Vulnerable Software and Affected Versions:

readarr version 0.4.15.2787

Description:

A SQL Injection issue exists in readarr that allows attackers to inject and execute arbitrary SQL commands against the backend SQLite database. The `/api/v1/wanted/cutoff` API endpoint does not properly sanitize user-supplied input to the `sortKey` parameter. Exploitation was confirmed using sqlmap via stacked queries, demonstrating the ability to run arbitrary SQL statements. A query utilizing SQLite's `RANDOMBLOB()` and `HEX()` functions was executed to simulate a time-based payload, indicating extensive control over database interactions.

Recommendations:

Update to a newer version that contains a fix for this issue.
