How to Fix CVE-2026-10804

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

streamlit fixed: 1.53.1 
pip install streamlit>=1.53.1
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 streamlit

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-10804, inspect your installed packages using pip:

pip show streamlit

Analyze the terminal output to locate any version of Streamlit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.53.1), your application is affected.

Note: The pip show streamlit 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 Streamlit, 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 has been found in Streamlit up to 1.53.0. Impacted is an unknown function in the library lib/streamlit/runtime/caching/hashing.py of the component Palette Handler. Such manipulation leads to use of weak hash. Local access is required to approach this attack. The attack requires a high level of complexity. The exploitability is considered difficult. The exploit has been disclosed to the public and may be used. The pull request to fix this issue awaits acceptance.
