FKIE_CVE-2025-67720

Vulnerability from fkie_nvd - Published: 2025-12-11 02:16 - Updated: 2025-12-12 15:18
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N
Summary
Pyrofork is a modern, asynchronous MTProto API framework. Versions 2.3.68 and earlier do not properly sanitize filenames received from Telegram messages in the download_media method before using them in file path construction. When downloading media, if the user does not specify a custom filename (which is the common/default usage), the method falls back to using the file_name attribute from the media object. The attribute originates from Telegram's DocumentAttributeFilename and is controlled by the message sender. This issue is fixed in version 2.3.69.
