⚡ An authenticated user can pull the rug out from under higher-privileged accounts! This vulnerability in GitLab could allow sneaky credential access and unauthorized actions. 🔥 Think of it like a hotel employee who can sneak into the management office and read guest files — just because they have a key to the building doesn't mean they should have access to everything! If exploited, this flaw could lead to an attacker gaining access to sensitive credentials of higher-privileged users, enabling them to perform actions as if they were those users. This could result in unauthorized changes, data leaks, or even total account takeovers, which is absolutely devastating for any organization!
