Summary
DIscourse doesn't prevent whispers to leak in excerpts
Details

Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, posts_nearby was checking topic access but then returning all posts regardless of type, including whispers that should only be visible to whisperers. Use Post.secured(guardian) to properly filter post types based on user permissions. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. No known workarounds are available.
