Detailsinfo

A vulnerability classified as problematic has been found in openml 2.0.20241110. Affected is an unknown code block of the component Token Handler. The manipulation with an unknown input leads to a password recovery vulnerability. CWE is classifying the issue as CWE-640. The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak. This is going to have an impact on confidentiality. CVE summarizes:

The openml/openml.org web application version v2.0.20241110 uses predictable MD5-based tokens for critical user workflows such as signup confirmation, password resets, email confirmation resends, and email change confirmation. These tokens are generated by hashing the current timestamp formatted as "%d %H:%M:%S" without incorporating any user-specific data or cryptographic randomness. This predictability allows remote attackers to brute-force valid tokens within a small time window, enabling unauthorized account confirmation, password resets, and email change approvals, potentially leading to account takeover.

This vulnerability is traded as CVE-2025-55796 since 08/16/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 11/18/2025). The MITRE ATT&CK project declares the attack technique as T1552.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
