- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 4.6.1.14, 5.0.0.42
- Published: 2025-12-18 · Updated: 2026-01-15

## Affected

- BullWall Ransomware Containment: from 4.6.0.0, fixed in 4.6.1.14; from 4.6.0.0, fixed in 5.0.0.42

## Description

BullWall Ransomware Containment supports configurable file and directory exclusions such as '$RECYCLE.BIN' to balance monitoring scope and performance. Certain exclusion patterns could allow an authenticated attacker to rename directories in a way that avoids monitoring. Fixed in 4.6.1.14 and 5.0.0.42, which remove hardcoded exclusion behavior and exposes exclusion handling as configurable settings.
