How to Fix CVE-2026-35052

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

dtale fixed: 3.22.0 
pip install dtale>=3.22.0
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 dtale

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-35052, inspect your installed packages using pip:

pip show dtale

Analyze the terminal output to locate any version of D-Tale in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.22.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In D-Tale, 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

### Impact Users hosting D-Tale publicly while using a redis or shelf storage layer could be vulnerable to remote code execution allowing attackers to run malicious code on the server. ### Patches Users should upgrade to version 3.22.0. ### Workarounds There are no workarounds for versions < 3.22.0
