How to Fix CVE-2026-2969

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

datapizza-ai-core fixed: Latest secure release 
pip install datapizza-ai-core>=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 datapizza-ai-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-2969, inspect your installed packages using pip:

pip show datapizza-ai-core

Analyze the terminal output to locate any version of datapizza-ai 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 datapizza-ai-core command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-791: Incomplete Filtering of Special Elements, where the product receives data from an upstream component, but does not completely filter special elements before sending it to a downstream component. In datapizza-ai, 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 flaw has been found in datapizza-labs datapizza-ai 0.0.2. Affected is the function ChatPromptTemplate of the file datapizza-ai-core/datapizza/modules/prompt/prompt.py of the component Jinja2 Template Handler. This manipulation of the argument Prompt causes improper neutralization of special elements used in a template engine. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
