Whenever a user tries to create a poll, a request containing gif URL or image id will be sent,
poll_question_data[options][][associated_image_id] contains the uploaded image id.
When this field value changes to any other images ID, that image will be shown in the poll.
After sending the request with another user image ID, a poll containing that image would be created.

If the poll creator deletes the Photo, it deletes victim images as well considering it as poll property.He reported the bug on November 3 and Facebook responds quickly and fixes the bug by 5 Nov 2017.

On November 8 Facebook Awarded $10,000 as bounty for his findings. Earlier this year Security researcher Dan Melamed came with a vulnerability that allows anyone to change the Video ID to any other video on the social media platform.

Before this Darabi found a couple of vulnerabilities with Facebook, in 2015, he found a CSRF on Facebook, and he was granted $15,000.
