CVE-2026-57310 JCD CVE debrief
CVE-2026-57310 involves Windu CMS's use of weak MD5 and SHA1 hashing algorithms with a static salt for storing user passwords. This implementation allows an attacker who obtains the password hash to potentially decode user credentials. The vulnerability has been confirmed in version 4.1, but may affect other versions due to limited information. Successful exploitation requires access to the hashed passwords.

Who should care
Administrators and users of Windu CMS, especially those using version 4.1, should be aware of this vulnerability. Developers and security professionals responsible for maintaining and securing instances of Windu CMS should prioritize patching or mitigating this issue to protect user credentials.
Technical summary
Windu CMS employs a weak hashing algorithm based on MD5 and SHA1 with a static salt to store user passwords. This insecure practice enables an attacker who gains access to the hashed passwords to potentially decode them and obtain user credentials. The vulnerability's impact is heightened by the use of static salt, which reduces the complexity for attackers. Confirmed in version 4.1, the vulnerability might also affect other versions. The CVSS score for this vulnerability is 6.3, indicating a medium severity level.
Defensive priority
Medium priority due to the potential for credential compromise. Immediate action is recommended to upgrade to a secure version or implement compensating controls.
Recommended defensive actions
- Upgrade Windu CMS to a version that uses a secure password hashing algorithm.
- Implement a compensating control, such as multi-factor authentication, to reduce the risk of credential compromise.
- Review and update password storage practices for all users and administrators.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
