How to Fix CVE-2023-28858

To remediate this vulnerability, upgrade all affected Redis dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

redis fixed: 4.4.3 
pip install redis>=4.4.3
redis fixed: 4.5.3 
pip install redis>=4.5.3
redis fixed: 4.3.6 
pip install redis>=4.3.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show redis

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-28858, inspect your installed packages using pip:

pip show redis

Analyze the terminal output to locate any version of Redis in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.3), your application is affected.

Note: The pip show redis command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-193: Off-by-one Error, where a product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value. In Redis, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

redis-py before 4.5.3, as used in ChatGPT and other products, leaves a connection open after canceling an async Redis command at an inopportune time (in the case of a pipeline operation), and can send response data to the client of an unrelated request in an off-by-one manner. The fixed versions for this CVE Record are 4.3.6, 4.4.3, and 4.5.3, but [are believed to be incomplete](https://github.com/redis/redis-py/issues/2665). CVE-2023-28859 has been assigned the issues caused by the incomplete fixes.
