CERT Polska coordinated the disclosure of CVE-2025-13822, an authentication bypass vulnerability affecting the MCPHub project in versions prior to 0.11.0. The flaw stems from certain endpoints not being protected by authentication middleware, which allows an unauthenticated attacker to perform actions on behalf of other users, effectively assuming their privileges.
The vulnerability was reported to CERT Polska by researcher Eryk Winiarz through the organization's coordinated vulnerability disclosure (CVD) process. No evidence of active exploitation is mentioned in the advisory, and the primary recommendation is for affected organizations to upgrade to MCPHub 0.11.0 or later.

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 16,570 reports from 147 sources, 725 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.
