⚡ A single trivial password can let anyone log in as any SAML user in OpenSlides prior to version 4.2.29! It's like a master key that works for every room in a hotel. 🏨 Think of it like a hotel where every guest has a unique keycard, but a lost master key allows access to any room without permission. This oversight means anyone could stroll right into sensitive meetings or agendas, causing chaos! An attacker could easily log in as any user synced via SAML using the local login form and a trivial password, potentially accessing confidential assembly information and manipulating agendas or elections. This could lead to unauthorized actions and absolutely devastating consequences for trust and security within your organization.
