A number of bugs in Tailscale leading to an RCE chain.

A long chain of issues going from blind SSRF to new-line injection to a blind Livestatus Query Language (LQL) injection to arbitrary file deletion and finally a race condition leading to authentication bypass.

The root of the issue is that XSLTC (turns XSLT into a Java Class to be executed for better performance) does not account for that fact that the `constant_pool_count` in a Java class is only 16bits. An attacker can create an XSLT document containing too many constants, all of which will be written to the class file, but the count will be truncated to 16bits, leading to some of those constants being interpreted as part of the classfile containing things like field and method descriptions for the class.

A somewhat simple security control bypass in Apache Batik's `DefaultScriptSecurity` and `DefaultExternalResourceSecurity` controls.Where Batik has to be able to load SVG files (and associated resources) from either a local or remote source, it makes for an interesting attack for SSRF and/or RCE...

There seems to be a lot of gaps in this writeup, but to the best of my understanding the bug a straight forward XSS but only in the MCS Webview giving access to the `window.GalaxyStore` object to download or open any application from the store.

So Java's Swing UI Toolkit in some cases will try to parse any strings that start with a `<` as HTML, and dangerously so as its handling of `
