Remote code execution in Telegram's bundled rlottie library allows an attacker to execute arbitrary code in the context of the current process when a victim opens a malicious Lottie/TGS animation. The flaw is a numeric truncation error (CWE-197) that results in an out-of-bounds write before the start of an allocated buffer, requiring user interaction (UI:R) and high attack complexity (AC:H) to exploit; the CVSS vector is AV:L, indicating a client-side file/content-handling issue. No public exploit has been identified at time of analysis, and no CISA KEV status is present.
One-click account takeover in Telegram Desktop before 7.2.9, where the Core::Sandbox inter-process communication layer fails to neutralize the semicolon record separator in URLs delivered through tg:// links. An attacker who gets a victim to open a crafted tg:// link can smuggle an extra OPEN: record into the IPC stream; that record is dispatched to the interpret: scheme handler, which uploads attacker-chosen local files - most damagingly the tdata session keys - to an attacker-controlled channel, giving full control of the victim's Telegram account. The issue is unauthenticated and needs no non-default configuration (CVSS PR:N, default install); the sole prerequisite is passive user interaction, namely opening the attacker-supplied link, and publicly available exploit code exists. CISA KEV does not list this issue as confirmed actively exploited.
Telegram Desktop before 6.9.4 fails to escape inline-keyboard button text when a chat is exported to HTML, so attacker-controlled button captions are written verbatim into the generated file and execute as script when the victim opens that HTML in a browser. Exploitation is tightly gated: the victim must have used the HTML export feature, must have an attacker-crafted message forwarded into a group they belong to (the original author does not need to be a group member), and must then open the resulting HTML file locally. Publicly available exploit code exists (an expatch.com writeup), but there is no confirmed active exploitation (not in CISA KEV); the vendor scores it 8.3 High under CVSS 4.0, while an independent reassessment places it lower as a user-interaction-gated, scope-changed XSS with limited confidentiality and integrity impact (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
Authorization bypass in the holaOS channel-gateway Telegram connector (holaOS through 2026.822.1) allows an attacker who registers a released Telegram username that appears in an operator's allowFrom list to submit turns to the bound workspace agent, which then runs the operator's configured tools on their machine. The root cause is that the connector authorizes senders by mutable Telegram username rather than by immutable numeric Telegram ID, yielding limited confidentiality and integrity impact (CVSS 4.0 base 6.3; independent assessment maps to CVSS 3.1 AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). Exploitation is opportunistic and targeted rather than reliably repeatable, since it requires an allowlisted username to be relinquished and re-registered by the attacker, and no public exploit was identified at time of analysis.
Null pointer dereference in Telegram Desktop up to version 6.7.5 allows remote attackers without authentication to cause denial of service by crafting a malicious login_url argument in the Bot API RequestButton function. The vulnerability requires user interaction to click a malicious link and has a public exploit disclosure, though vendor response to early disclosure notification was not forthcoming.
