CVE-2026-33954: LinkAce discloses private notesto unauthorized authenticated users via the web link detail page
LinkAce is a self-hosted archive to collect website links. In versions prior to 2.5.3, a private note attached to a non-private link can be disclosed to a different authenticated user via the web interface. The API appears to correctly enforce note visibility, but the web link detail page renders notes without applying equivalent visibility filtering. As a result, an authenticated user who is allowed to view another user's internal or public link can read that user's private notes attached to the link. Version 2.5.3 patches the issue.
