bludit: Improper Removal of Sensitive Information Before Storage or Transfer
CVE-2026-46657 is a high-severity improper removal of sensitive information before storage or transfer vulnerability in bludit, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected bludit versions: < 3.22.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
Bludit is a content management system. Versions prior to 3.22.0 have a vulnerability in the user management logic that allows deactivated accounts to maintain access via persistent authentication tokens. When an administrator disables a user account, the application fails to invalidate or clear the associated tokenAuth and tokenRemember fields in the JSON database. Consequently, any user with a pre-existing "Remember Me" cookie can bypass the account disablement and maintain a valid authenticated state. Version 3.22.0 patches the issue.

The underlying weakness: Improper Removal of Sensitive Information Before Storage or Transfer
The product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors.
How developers prevent this class of flaw
- Clearly specify which information should be regarded as private or sensitive, and require that the product offers functionality that allows the user to cleanse the sensitive information from the resource before it is published or exported to other parties.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
- Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
