How to Fix CVE-2026-10812

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

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

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-10812, inspect your installed packages using pip:

pip show gptcache

Analyze the terminal output to locate any version of GPTCache 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 gptcache command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In GPTCache, 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 detected in zilliztech GPTCache up to 0.1.44. Affected by this issue is the function BufferedReader.peek of the file gptcache/processor/pre.py of the component Cache Key Handler. Performing a manipulation of the argument input_data["image"] results in use of weak hash. The attack must be initiated from a local position. The attack is considered to have high complexity. The exploitation is known to be difficult. The exploit is now public and may be used. The pull request to fix this issue awaits acceptance.
