CVE-2018-17780 describes an IP address leakage vulnerability in Telegram Desktop 1.3.14 and Telegram 3.3.0.0 WP8.1 on Windows. This medium severity flaw (CVSS 6.5) stems from an unsafe default behavior where P2P connections for calls are accepted from contacts outside the user's "My Contacts" list, allowing an attacker to discover a user's public and private IP addresses. The attack requires low privileges and no user interaction, leading to a high confidentiality impact. While there is no evidence of active exploitation or public exploit code, the vulnerability has garnered significant community discussion and media coverage, indicating awareness of the issue.
