CVE-2026-32722

LOW

Memray-generated HTML reports vulnerable to Stored XSS via unescaped command-line metadata

Title source: cna

Description

Memray is a memory profiler for Python. Prior to Memray 1.19.2, Memray rendered the command line of the tracked process directly into generated HTML reports without escaping. Because there was no escaping, attacker-controlled command line arguments were inserted as raw HTML into the generated report. This allowed JavaScript execution when a victim opened the generated report in a browser. Version 1.19.2 fixes the issue.
