Смысл: The text demonstrates how a small oversight in a feature (bookmarks) combined with predictable ID generation can lead to a massive privacy breach, allowing unauthorized access to private user media.
A security researcher discovered a VK vulnerability that allowed the extraction of direct links to any private photo by leveraging the bookmarks feature and API bruteforcing.
Смысл: The main idea is to demonstrate how a discrepancy between the desktop and mobile versions of a platform can lead to security leaks, specifically allowing unauthorized access to private user content through metadata and thumbnails.
A security researcher discovered a VK vulnerability that allowed viewing thumbnails of private photos and identifying users who liked them, earning a $700 bounty.
Смысл: The text illustrates how a simple sequential ID system for file uploads can lead to a critical security vulnerability, allowing users to steal invites from others.
An individual gained access to Habr by exploiting a sequential ID vulnerability in the invite upload system and was later rewarded with a legal invite for reporting it.
