CVE-2026-112178 · MISP Proposal ACL Bypass: Incomplete Distribution Level Check in Shadow Attribute Access Control
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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
