CVE-2024-6423 PUBLISHED

Sensitive Data Exposure via URL Parameters in Multiple WSO2 Products Allows Confidential Information Leakage

Assigner: WSO2
Reserved: 01.07.2024 Published: 21.10.2026 Updated: 21.10.2026

The product failed to enforce validation constraints on user-supplied input in URL parameters, allowing sensitive data to be passed to flows where it was not intended to be processed. Although the product did not utilize this data, its acceptance could lead to logging.

If a user mistakenly sends sensitive data via URL parameters to any flow, this data could be inadvertently logged in access logs. This has the potential to expose confidential information, compromising the security and privacy of affected systems if the product is used incorrectly.
