What is CVE-2022-23853?

The LSP plugin in KDE Kate and KTextEditor can lead to security issues due to its attempts to execute an LSP server binary when opening certain file types. If the binary is not in the PATH, it erroneously searches the directory of the opened file to find the binary, potentially introducing risks through untrusted directories. This flaw arises from a misunderstanding of the QProcess API, which could be exploited if a malicious file is opened.
