CVE-2026-41526

Estado: AnalizadaAlta (7.8)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Requiere interacción del usuario (UI:R) para abrir archivo preparado. Escape de shell vía metacaracteres en KShell::quoteArgs permite ejecución de comandos arbitrarios. Potencial acceso a credenciales tras ejecución.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
