CVSS 7.3 · HIGH

CVE-2026-41355

OpenShell before 2026.3.28 contains an arbitrary code execution vulnerability in mirror mode that converts untrusted sandbox files into workspace hooks. Attackers with mirror mode access can execute arbitrary code on the host during gateway startup by exploiting enabled workspace hooks.

How to read this card

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — máxima severidad teórica. Explotable de forma remota, sin privilegios, con impacto total. Aún no confirmada como explotada en el mundo real, pero parchea ya.
