Shreateh said he contacted Facebook security about the vulnerability before using it to post to Mark Zuckerberg's page.
A Palestinian researcher posted a message on Facebook CEO Mark Zuckerberg’s page last week after he says the site’s security team didn’t take his warnings about a security flaw seriously.
"First, sorry for breaking your privacy and post(ing) to your wall," wrote Khalil Shreateh. "I (have) no other choice to make after all the reports I sent to (the) Facebook team."
