Alias: CVE-2022-23853: The LSP (Language Server Protocol) plugin in KDE Kate before 21.12.2 and KTextEditor before 5.91.0 tries to execute the associated LSP server binary when opening a file of a given type. If this binary is absent from the PATH, it will try running the LSP server binary in the directory of the file that was just opened (due to a misunderstanding of the QProcess API, that was never intended). This can be an untrusted directory.
I thought I'd filed bugs for this but note that (thanks to asturm for pointing it out) it's one or t'other -- the frameworks fix covers Kate too.
