By now, everyone should know that Instagram is prone to security vulnerabilities and has been in constant lockdown since early August.
Instagram also suffered a hack that allowed attackers to steal user data in July.
But a new vulnerability that Instagram reported on Friday, dubbed “Fingerprinting” has apparently exposed the personal data of users, even if they are not logged in.
It was only discovered after Instagram announced a fix, but now the bug has been patched.
The bug affects all Instagram users who have logged into Instagram via the site’s login page.
As noted by security researcher @nkirby, the vulnerability exists on all platforms.
Fingerprints are a series of text and image fields that Instagram users can use to log into Instagram and sign in to the site.
For example, a user could enter a text field that read “facebook login” and “facebook,” and then the user could use the keyboard to enter “facebook.”
The bug, which was first reported on Tuesday, is not exploitable on all Instagram platforms, but Instagram has fixed the vulnerability on its mobile apps and desktop apps.
If a user is not logged into their account, they are unable to view any Instagram content or photos, and can only upload a short clip to Instagram.
The flaw was discovered by security researchers at Twitter, which discovered the flaw in June.
The Twitter security team said that the bug was discovered because “the user has already used Instagram to sign in with their Facebook login and not with a password.”
The flaw was fixed in the last update to Instagram, which took effect in August.
