kf6-kcoreaddons vulnerability
It was discovered that KCoreAddons incorrectly handled shell argument quoting in KShell::quoteArgs. The parsing did not adequately handle shell metacharacters, which could lead to a shell escape. An attacker could possibly use this issue to execute arbitrary commands in applications that relied on this method to handle user input.
