Yesterday a vulnerability was discovered that made it possible to inject malicious code into an image link on Imgur. From our team’s analysis, it appears the exploit was targeted specifically to users of 4chan and 8chan via images shared to a specific sub-reddit on Reddit.com using Imgur’s image hosting and sharing tools. The affected images were not published to the galleries on Imgur.com.
The vulnerability was patched yesterday evening and we’re no longer serving affected images, but as a precaution we recommend that you clear your browsing data, cookies, and localstorage.
As we learn more about the nature of the issue, we’ll update this post. In the meantime, if you have any questions, we’d be happy to address them at
