What is CVE-2026-71463?

A vulnerability in the Jinja template system allows for improper verification of dynamic data via static AST inspections. This oversight leads to the potential execution of unintended logic based on dynamic subscripts and conditional statements. Consequently, sensitive information, including install paths, Python versions, and source line number details can be leaked through the notification body sent to an attacker-controlled webhook URL. This poses risks of exposing critical data points that can be exploited maliciously.
