CVE-2024-41259Network attack vector

Account data manipulation via MD5 Gravatar hashes

Published Aug 1, 2024 · Updated Aug 2, 2024

Improper cryptography in Navidrome 0.52.3 and earlier allows remote attackers to manipulate account information through Gravatar URLs. The Gravatar integration hashes each user's email address with MD5 and embeds the digest in the avatar URL rather than using SHA-256. Exploitation requires an attacker-controlled email producing the relevant digest; the disclosure presents no demonstrated collision or broader account-takeover path.
