What is CVE-2022-23853?
CVE-2022-23853 is a high-severity command injection vulnerability in n/a, published on 11 Feb 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-427
