CERT Polska coordinated the responsible disclosure of multiple critical and high-severity vulnerabilities affecting Raytha CMS, an open-source content management system. The most severe issue is CVE-2025-15540, which allows privileged users to execute arbitrary .NET code through the 'Functions' module due to lack of sandboxing, enabling complete compromise of the hosting environment. Additional vulnerabilities include a host header injection flaw (CVE-2025-69240) that enables account takeover via password reset token theft, and server-side request forgery (CVE-2025-69239) in the theme import functionality.
The vulnerability set also encompasses eight stored and reflected cross-site scripting (XSS) issues across multiple parameters in post editing, page creation, profile management, and authentication flows. Cross-site request forgery (CSRF) protection is missing across multiple endpoints (CVE-2025-69238), allowing attackers to perform unauthorized actions on behalf of authenticated users. Authentication security is further weakened by user enumeration in password reset (CVE-2025-69243) and complete absence of brute-force protection (CVE-2025-69246).
The vendor has released patches addressing these issues across two versions: CVE-2025-69243 was fixed in version 1.5.0, while the remaining ten vulnerabilities were addressed in version 1.4.6. Organizations running Raytha CMS should immediately upgrade to the latest patched version. The vulnerabilities were discovered by Daniel Basta with support from Patryk Kieszek, following CERT Polska's coordinated vulnerability disclosure process.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
