Security Advisory: express-xss-sanitizer
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
- 2.0.1 and later
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.
Impact
An attacker could cause denial-of-service by sending a request with deeply nested structures, potentially crashing the Node.js process.
Solution
Upgrade to version 2.0.1 or later:
npm install express-xss-sanitizer@latest - Database specific
