How to Fix CVE-2026-11312

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

infinistore fixed: Latest secure release 
pip install infinistore>=Latest secure release
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 infinistore

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-11312, inspect your installed packages using pip:

pip show infinistore

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

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-404: Improper Resource Shutdown or Release, where the product does not release or incorrectly releases a resource before it is made available for re-use. In bytedance InfiniStore, 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

A vulnerability was found in bytedance InfiniStore up to 0.2.33. The impacted element is the function purge_kv_map in the library /src/infinistore.h of the component KV Map Handler. Performing a manipulation results in inefficient algorithmic complexity. The attack requires a local approach. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
