CVE-2025-1979
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVersions of the package ray before 2.43.0 are vulnerable to Insertion of Sensitive Information into Log File where the redis password is being logged in the standard logging. If the redis password is passed as an argument, it will be logged and could potentially leak the password. This is only exploitable if: 1) Logging is enabled; 2) Redis is using password authentication; 3) Those logs are accessible to an attacker, who can reach that redis instance. **Note:** It is recommended that anyone who is running in this configuration should update to the latest version of Ray, then rotate their redis password.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisSensitive values — secrets, tokens, session identifiers, personal data — are written into log files, so anyone with access to the logs, which is often a broad group, obtains them. It turns a routine diagnostic into a credential leak. The fix is redacting sensitive data before it is logged and tightly restricting who can read the logs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedray >= 2.43.0
- 1. Stop any running Ray instances that may be using the vulnerable version
- 2. Back up your current Ray configuration files and any custom scripts that handle Redis passwords
- 3. Upgrade Ray to version 2.43.0 or later by running: pip install --upgrade ray>=2.43.0 (or your package manager's equivalent)
- 4. Verify the upgrade was successful by checking the installed version: python -c 'import ray; print(ray.__version__)'
- 5. After upgrading, rotate your Redis password that was previously exposed in logs, as it may have been compromised
- 6. Restart Ray services with the new version
- 7. Confirm logs no longer contain Redis password by examining recent log output
