Overview
A vulnerability was discovered in express-xss-sanitizer that allowed unbounded recursion depth during sanitization of nested objects.
Affected Versions
- All versions prior to 2.0.1
Patched Versions

Description
The sanitize function in lib/sanitize.js performed recursive sanitization without depth limiting, making it vulnerable to stack overflow attacks via specially crafted deeply nested JSON objects.
