⚠️ This use-after-free vulnerability can lead to a crash in your favorite email client! Imagine a juggler dropping a ball mid-performance and chaos following! 🎪 Think of it like a restaurant that continues to serve a dish after the chef has already taken it off the menu.

If exploited, this could lead to crashes that disrupt your workflow, causing potential data loss and frustration. While it’s not confirmed as actively exploited, the possibility of a rogue chef throwing a wrench in your meal is a concern!
