• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days

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.

Affected products

• bloomberg memray: before 1.19.2 — fixed in 1.19.2

How to fix

Upgrade to a fixed version: bloomberg memray 1.19.2. Check the vendor advisory for mitigations.
