The vulnerabilities described in this paper have been partially known in security research communities since at least 2016. However, Deezer has not publicly announced plans to deprecate the ARL token. Responsible disclosure attempts by third-party researchers have received acknowledgments but no concrete remediation timelines as of 2025. If you want, I can: curl -s "https://api
Deezer’s Terms of Service prohibit automated access, scraping, or any use of the API without explicit authorization. Using an extracted ARL token for any purpose other than legitimate user access (e.g., forensic analysis without a warrant) constitutes a violation and potentially computer fraud in jurisdictions with strict cybercrime laws (CFAA in the US, Computer Misuse Act in the UK). Because the token is a "live" representation of
While the ARL token provides significant flexibility, it carries inherent risks. Because the token is a "live" representation of an account session, sharing it is equivalent to sharing a password. Security researchers note several dangers:
When you log into Deezer via a web browser or mobile app, the platform’s servers generate a unique session identifier. For standard web browsing, this is often stored in cookies. However, for Deezer’s API (Application Programming Interface)—which powers features like playlist synchronization, track streaming, and user data retrieval—the ARL token is the preferred method.
Treat ARL as a sensitive session credential: use official APIs when building integrations, protect cookies, and follow Deezer’s terms to avoid account risk.
