CVE-2026-26157

7.0 highEPSS 0.7%

High (7.0). EPSS 0.7% chance of exploitation in the next 30 days.

A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files.
