CVE-2021-41861

NVD-CWE-noinfoPublished: October 4, 2021· Updated: Jun 17, 2026

3.3
CVSS v3.1

Official Description

The Telegram application 7.5.0 through 7.8.0 for Android does not properly implement image self-destruction, a different vulnerability than CVE-2019-16248. After approximately two to four uses of the self-destruct feature, there is a misleading UI indication that an image was deleted (on both the sender and recipient sides). The images are still present in the /Storage/Emulated/0/Telegram/Telegram Image/ directory.
