⚠️ Heap corruption might sound scary, but this one’s hiding in plain sight! In Foxit PhantomPDF versions before 8.3.10, an issue sneaks in when adding AcroForms. 💻 Think of it like a waiter trying to take an order from several tables at once, leading to a mix-up in the kitchen. The disorganization can cause the system to serve a completely incorrect dish – or in this case, corrupt data. If exploited, this heap corruption could lead to unexpected behavior or crashes in the application, affecting your workflows. While it doesn't seem to be actively exploited, the potential for data loss or disruption is definitely not something to overlook.
