This removes the message from other people\u2019s inboxes. However while the app was removing messages, images and videos that were sent and later unsent where still saved on a users device. <\/p>\n\n\n\n<p>Dhiraj Mishra, the security researcher who found the privacy issue, <a href=\"https:\/\/www.inputzero.io\/2019\/09\/telegram-privacy-fails-again.html?\/telegram-privacy-fails.html\">published his findings in a blogpost<\/a>. (<a href=\"https:\/\/techcrunch.com\/2019\/09\/09\/telegram-bug-delete-unsent-photos\/\">According to TechCrunch<\/a> Mishra also shared his findings exclusively with TechCrunch, a strange use of  exclusively, but I digress.) Said the Android version of Telegram was permanently storing photos and videos in the device\u2019s internal storage. Saying a users would still have a sent and unsent image stored under `<strong>\/Telegram\/Telegram Images\/`&nbsp;<\/strong>folder, Dhiraj concluded that the feature was only deleting the image from the chat window.<\/p>\n\n\n\n<p>In the blogpost Mishra shares the process used by&nbsp;competing apps, with a similar unsend message feature. In WhatsApp a feature called &#8220;Delete for everyone&#8221; was in fact deleting the media from the device. Once a phone was effectively unsent, it was fully removed `<strong>\/Whatsapp\/Whatsapp Media\/Whatsapp Images\/<\/strong>` folder. WhatsApp also required the same permission as Telegram when it comes to storage which is `read\/write\/modify`.<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"container-lazyload preview-lazyload container-youtube js-lazyload--not-loaded\"><a href=\"https:\/\/www.youtube.com\/watch?v=cK1AphjY3Ho\" class=\"lazy-load-youtube preview-lazyload preview-youtube\" data-video-title=\"Telegram Incorrect ACL\" title=\"Play video &quot;Telegram Incorrect ACL&quot;\">https:\/\/www.youtube.com\/watch?v=cK1AphjY3Ho<\/a><noscript>Video can&#8217;t be loaded because JavaScript is disabled: <a href=\"https:\/\/www.youtube.com\/watch?v=cK1AphjY3Ho\" title=\"Telegram Incorrect ACL\">Telegram Incorrect ACL (https:\/\/www.youtube.com\/watch?v=cK1AphjY3Ho)<\/a><\/noscript><\/div>\n<\/div><\/figure>\n\n\n\n<p>According to Mishra&#8217;s blog post, this issue holds true for Telegram &#8220;supergroups&#8221; as well. He gives an example of a case where a user is part of a group with 2,000,00 members and accidentally shares an image. When that person clicks &#8220;delete for all members&#8221; they were relying on a broken functionality. As the files would still be present in storage for all users phones.<\/p>\n\n\n\n<p>Mishra says the Affected version of telegram is the latest stable version (5.10.0 (1684)) of Telegram for Android. He says while he didn&#8217;t try this with Telegram for iOS or Windows, he does assume this issue\u00a0would\u00a0exist for those platforms. This issue didn&#8217;t impact users who utilized the feature of &#8220;<strong>New Secret Chat<\/strong>&#8221; in Telegram where no such traces of media where left.<\/p>\n\n\n\n<p>The good<strong> <\/strong>news, Mishra says he submitted this to Telegram sec-team and the team fix the problem, he was also awarded \u20ac2,500 by Telegram.<\/p>\n\n\n\n<p>To be clear this is a problem more around privacy than true security. It has been fixed and telegram, handled this problem in a way befitting a company whose focus is privacy and security.  <\/p>\n\n\n\n<p>Header Image: Dhiraj Mishra<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Telegram, a privacy focused messaging app with millions of users, has fixed a bug allowing users to recover media that was \u2018unsent\u2019 by other people.
