CVE-2026-105643
Ghost is a Node.js content management system. From version 6.34.0 until 6.67.0, embed cards in the Ghost editor could bypass protections against stored cross-site scripting. Any staff user, including Contributors, could store scripts in post content that ran when another staff user opened the post in the editor, potentially compromising that user’s admin session. Self-hosted sites should leave the new security.embedPreviewUrl configuration option at its default value. This issue is fixed in version 6.67.0.

CVE-2026-105635
Plane is an open-source project management tool. Prior to 1.4.0, ProjectJoinEndpoint at GET /api/workspaces/{slug}/projects/{project_id}/join/{pk}/ uses permission_classes = [AllowAny] and returns the full ProjectMemberInvite record, including its email, token, and role, to unauthenticated callers. The corresponding POST endpoint checks only whether the submitted email matches project_invite.email and does not validate the invitation token. An attacker who knows the invitation UUID can discover the invited email, register an account with that email, and accept the invitation without receiving the original invite. This issue is fixed in 1.4.0.

CVE-2026-105634
Plane is an open-source project management tool. Prior to 1.3.0, the ProjectMemberViewSet.partial_update method allows any project member, including a user with the lowest GUEST role, to modify another project member's role. The authorization check prevents assigning a role higher than the requester's role but does not prevent assigning a lower or equal role, allowing a Guest to demote Administrators and Members and deny them project control. This vulnerability is fixed in 1.3.0.
