What is CVE-2025-34114?

A security misconfiguration vulnerability in the OpenBlow whistleblowing platform arises from the lack of vital HTTP response headers, such as Content-Security-Policy, Referrer-Policy, Permissions-Policy, Cross-Origin-Embedder-Policy, and Cross-Origin-Resource-Policy. This oversight diminishes browser-level security defenses, rendering users susceptible to various attacks, including cross-site scripting (XSS), clickjacking, and referer leakage. While some deployments make attempts to implement CSP through HTML tags, this approach is inadequate, as contemporary browsers depend on header-based configurations for effective enforcement against inline scripts and untrusted resources.

Exploit Proof of Concept (PoC)
