Versions prior to 2.25.0 are vulnerable to an unauthenticated Regular Expression Denial of Service (ReDoS) attack within the WebSocket subscription handling logic. By injecting unescaped regex metacharacters into the `context` parameter of a stream subscription, an attacker can force the server&#39;s Node.js event loop into a catastrophic backtracking loop when evaluating long string identifiers (like the server&#39;s self UUID). This results in a total Denial of Service (DoS) where the server CPU spikes to 100% and becomes completely unresponsive to further API or socket requests. Version 2.25.0 contains a fix.</p> <p>Signal K Server is a server application that runs on a central hub in a boat.

The `contextMatcher()` and `pathMatcher()` functions convert wildcard strings (e.g., `*`) into regular expressions to match incoming data against client subscriptions.</p> <p>While the code attempts to escape `.` and `*` characters, it fails to escape other dangerous regular expression metacharacters—such as `+`, `(`, `)`, `?`, `[`, and `]`. Because of this, an attacker can submit a crafted `context` that contains nested quantifiers (e.g., `([a-z0-9:-]+)+!`). When the server attempts to test this malicious regex against legitimate, lengthy data identifiers (like `vessels.urn:mrn:signalk:uuid:d384dc156010`), the regex engine fails to find a match at the end of the string but initiates billions of catastrophic backtracking operations trying to resolve the nested combinations.
