# CVE-2025-13647: Information Disclosure in Multiple WSO2 Products Allows Exposure of Certificate File Paths

Status: published. Published: 2026-11-02. Updated: 2026-11-02.

The affected component fails to enforce expected validation constraints on the `content-type` header when processing certain requests. This allows an attacker to submit a crafted request with a manipulated `content-type` header.

Successful exploitation can lead to the unintended exposure of the file paths for certificate files. This information disclosure could potentially be leveraged in subsequent attacks or compromise the confidentiality of the system.
