CVE-2025-55796 describes a critical vulnerability in openml/openml.org version v2.0.20241110, where predictable MD5-based tokens are used for essential user functions like signup and password resets. These tokens, generated solely from timestamps, lack cryptographic randomness, making them susceptible to brute-force attacks. With a CVSS score of 7.5 (HIGH), this flaw allows remote attackers to bypass authentication and potentially achieve account takeover due to unauthorized confirmation of accounts, password resets, or email changes. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
