Detailsinfo

A vulnerability was found in readarr 0.4.15.2787 and classified as critical. This issue affects some unknown functionality of the file /api/v1/wanted/cutoff of the component API Endpoint. The manipulation of the argument sortKey with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

SQL Injection vulnerability exists in the sortKey parameter of the GET /api/v1/wanted/cutoff API endpoint in readarr 0.4.15.2787. The endpoint fails to properly sanitize user-supplied input, allowing attackers to inject and execute arbitrary SQL commands against the backend SQLite database. Sqlmap confirmed exploitation via stacked queries, demonstrating that the parameter can be abused to run arbitrary SQL statements. A heavy query was executed using SQLite's RANDOMBLOB() and HEX() functions to simulate a time-based payload, indicating deep control over database interactions.
