Instagram has addressed a new flaw, which allows everyone to access private profiles without having to follow them and also lets them view archived posts and stories.
The Facebook group recently rewarded an Indian programmer and Bug Bounty Hunter with Rs 22 lakh to identify the Instagram bug that can permit anybody, without following, to view different posts on a private Instagram account. The issue that the programmer, Mayur Fartade, has just reported on a media post might've been a big privacy violation that leads to target identity fraud and harassment given the hazards posed by it. On April 15, 2021, this flaw was notified to Instagram and now it is patched.
The flaw might have enabled hackers or those intending to cyber spy – to target particular users' posts and gain access without having to follow their private account, according to Fartade.
Fartade noted in his post that the high privileges which attackers may have gained would be utilized for looking at elements like “private/archived posts, stories, reels (and) IGTV, details including like/comment/save count, display_url, image. uri, Facebook linked page(if any) and other particulars, without following the user and by using Media ID”.
The flaw may allow any brute person to force a "Media ID" post which is an ID for any post created on Instagram and then use it to regenerate legitimate links to archived posts and private posts. For this purpose, attackers can use the Instagram GraphQL tool on their developer library, input any targeted post's brute-forced media ID, and execute the tool to gain access to information such as the post link and other related details.
