⚠️ Sensitive data is hiding in plain sight! The o2oe E-Invoice App Malaysia has a vulnerability that allows unauthorized access to embedded sensitive information — think of it as leaving your diary out in the open without a lock. 📖🔓 Imagine you’re hosting a party and you leave your guest list pinned to the front door. Anyone passing by can see who’s invited, which can lead to uninvited guests crashing the party. This vulnerability is like that — sensitive data is exposed to unauthorized users just waiting to take advantage of it. An attacker could exploit this vulnerability to retrieve sensitive system information, potentially leading to unauthorized access or manipulation of the invoicing system. While the impact might not be catastrophic, it’s certainly a risk you don’t want hanging around like that one party crasher nobody invited!
