CVE-2025-50983: SQL Injection vulnerability exists in the sortKey parameter of the GET /api/v1/wanted/cutoff API endpoint in readarr 0.4.15.2787.

SQL Injection vulnerability exists in the sortKey parameter of the GET /api/v1/wanted/cutoff API endpoint in readarr 0.4.15.2787.

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.

What it means for a small business

If your business uses Readarr, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.35%, higher than 28% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
