CVE-2026-112178
MISP contains an access control flaw in the proposal (shadow attribute) visibility logic.
Overview
CVE-2026-112178 is a known-severity vulnerability. It was published on October 19, 2026.
Technical description
MISP contains an access control flaw in the proposal (shadow attribute) visibility logic. The authorization check accepted any attribute or object carrying one of the user's sharing groups without verifying the distribution level, and denied the owning organisation access to proposals on its own organisation-only attributes.
- A user belonging to a sharing group could view proposals on attributes or objects with that sharing group, regardless of the attribute's distribution level (levels 1-3 should restrict visibility)
- The owning organisation could not view proposals on its own org-only attributes
Security impact: Unauthorized disclosure of proposed attribute changes to users who should not have access based on distribution level restrictions.
Affected: <2.5.48
Remediation
