What it is

⚡ An authenticated user can peek at offers meant for others, just by changing a simple number in the URL! This Insecure Direct Object Reference (IDOR) vulnerability might seem small, but it opens the door to serious privacy issues. 😱 Think of it like a shared office where everyone has a filing cabinet with their client contracts. If some sneaky employee knows how to tweak the filing cabinet ID, they can sneakily access their colleague’s sensitive contracts – a recipe for disaster! 🗂️ An attacker could potentially access quotes and sensitive client information that don’t belong to them, leading to unauthorized access and trust issues. This is particularly concerning when dealing with private client data, as the repercussions can be absolutely devastating! 🔥

Put simply

Think of it like a shared office where everyone has a filing cabinet with their client contracts. If some sneaky employee knows how to tweak the filing cabinet ID, they can sneakily access their colleague’s sensitive contracts – a recipe for disaster! 🗂️ The vulnerability arises from missing authorization checks in the offer view functionality of the teklifolustur_app. Authenticated users can manipulate the offer_id parameter to access other users' offers, bypassing intended restrictions.
