What is CVE-2021-41861?

The Telegram application for Android, versions 7.5.0 to 7.8.0, is susceptible to a vulnerability where the self-destruction feature for images does not function as intended. Users may believe that their images have been deleted after using the feature two to four times, as indicated by a misleading user interface on both sender and recipient sides. However, the images remain stored in the device's directory, posing a risk to user privacy and data security.
