CVE-2026-41526: Kde Kcoreaddons

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Kde Kcoreaddons: before 6.25.0 (fixed in 6.25.0)
