CVE-2026-41526

In KDE KCoreAddons before 6.25, KShell::quoteArgs is intended to safely quote arguments so that they can be passed to a shell command. This parsing does not adequately handle metacharacters, leading to an escape from the shell. All applications relying on this method in a security-critical path to handle user input are affected and could be exploited. In particular, because sendInput() sends a string to a terminal, a control character such as \x01 can be used during injection.

Summary		(es) En KDE KCoreAddons anterior a 6.25, KShell::quoteArgs está diseñado para entrecomillar argumentos de forma segura para que puedan pasarse a un comando de shell. Este análisis no maneja adecuadamente los metacaracteres, lo que lleva a un escape del shell. Todas las aplicaciones que dependen de este método en una ruta crítica de seguridad para manejar la entrada del usuario se ven afectadas y podrían ser explotadas. En particular, debido a que sendInput() envía una cadena a un terminal, un carácter de control como \x01 puede usarse durante la inyección.
