| CVE-2018-20436 | 1 Telegram | 2 Telegram, Web | 2024-08-05 | N/A |
| The "secret chat" feature in Telegram 4.9.1 for Android has a "side channel" in which Telegram servers send GET requests for URLs typed while composing a chat message, before that chat message is sent. There are also GET requests to other URLs on the same web server. This also affects one or more other Telegram products, such as Telegram Web-version 0.7.0. In addition, it can be interpreted as an SSRF issue. NOTE: a third party has reported that potentially unwanted behavior is caused by misconfiguration of the "Secret chats > Preview links" setting | ||||
| CVE-2018-15543 | 1 Telegram | 1 Telegram | 2024-08-05 | N/A |
| An issue was discovered in the org.telegram.messenger application 4.8.11 for Android. The FingerprintManager class for Biometric validation allows authentication bypass through the callback method from onAuthenticationFailed to onAuthenticationSucceeded with null, because the fingerprint API in conjunction with the Android keyGenerator class is not implemented. In other words, an attacker could authenticate with an arbitrary fingerprint. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred | ||||
| CVE-2018-15542 | 1 Telegram | 1 Telegram | 2024-08-05 | N/A |
| An issue was discovered in the org.telegram.messenger application 4.8.11 for Android. The Passcode feature allows authentication bypass via runtime manipulation that forces a certain method's return value to true. In other words, an attacker could authenticate with an arbitrary passcode. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred | ||||
| CVE-2018-3986 | 1 Telegram | 1 Telegram | 2024-08-05 | 5.5 Medium |
| An exploitable information disclosure vulnerability exists in the "Secret Chats" functionality of the Telegram Android messaging application version 4.9.0. The "Secret Chats" functionality allows a user to delete all traces of a chat, either by using a time trigger or by direct request. There is a bug in this functionality that leaves behind photos taken and shared on the secret chats, even after the chats are deleted. These photos will be stored in the device and accessible to all applications installed on the Android device. | ||||
| CVE-2019-16248 | 1 Telegram | 1 Telegram | 2024-08-05 | 5.5 Medium |
| The "delete for" feature in Telegram before 5.11 on Android does not delete shared media files from the Telegram Images directory. In other words, there is a potentially misleading UI indication that a sender can remove a recipient's copy of a previously sent image (analogous to supported functionality in which a sender can remove a recipient's copy of a previously sent message). | ||||
| CVE-2019-15514 | 1 Telegram | 1 Telegram | 2024-08-05 | N/A |
| The Privacy > Phone Number feature in the Telegram app 5.10 for Android and iOS provides an incorrect indication that the access level is Nobody, because attackers can find these numbers via the Group Info feature, e.g., by adding a significant fraction of a region's assigned phone numbers. | ||||
| CVE-2019-10044 | 2 Microsoft, Telegram | 3 Windows, Telegram, Telegram Desktop | 2024-08-04 | N/A |
| Telegram Desktop before 1.5.12 on Windows, and the Telegram applications for Android, iOS, and Linux, is vulnerable to an IDN homograph attack when displaying messages containing URLs. This occurs because the application produces a clickable link even if (for example) Latin and Cyrillic characters exist in the same domain name, and the available font has an identical representation of characters from different alphabets. | ||||
| CVE-2020-12474 | 1 Telegram | 2 Telegram, Telegram Desktop | 2024-08-04 | 6.5 Medium |
| Telegram Desktop through 2.0.1, Telegram through 6.0.1 for Android, and Telegram through 6.0.1 for iOS allow an IDN Homograph attack via Punycode in a public URL or a group chat invitation URL. | ||||
| CVE-2020-10570 | 1 Telegram | 1 Telegram | 2024-08-04 | 6.1 Medium |
| The Telegram application through 5.12 for Android, when Show Popup is enabled, might allow physically proximate attackers to bypass intended restrictions on message reading and message replying. This might be interpreted as a bypass of the passcode feature. | ||||
| CVE-2021-41861 | 1 Telegram | 1 Telegram | 2024-08-04 | 3.3 Low |
| 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. | ||||
| CVE-2021-36769 | 1 Telegram | 2 Telegram, Telegram Desktop | 2024-08-04 | 5.3 Medium |
| A reordering issue exists in Telegram before 7.8.1 for Android, Telegram before 7.8.3 for iOS, and Telegram Desktop before 2.8.8. An attacker can cause the server to receive messages in a different order than they were sent a client. | ||||
| CVE-2021-30496 | 1 Telegram | 1 Telegram | 2024-08-03 | 5.7 Medium |
| The Telegram app 7.6.2 for iOS allows remote authenticated users to cause a denial of service (application crash) if the victim pastes an attacker-supplied message (e.g., in the Persian language) into a channel or group. The crash occurs in MtProtoKitFramework. NOTE: the vendor's perspective is that "this behavior can't be considered a vulnerability." | ||||
| CVE-2021-31315 | 1 Telegram | 1 Telegram | 2024-08-03 | 5.5 Medium |
| Telegram Android <7.1.0 (2090), Telegram iOS <7.1, and Telegram macOS <7.1 are affected by a Stack Based Overflow in the blit function of their custom fork of the rlottie library. A remote attacker might be able to access Telegram's stack memory out-of-bounds on a victim device via a malicious animated sticker. | ||||

| Telegram Android <7.1.0 (2090), Telegram iOS <7.1, and Telegram macOS <7.1 are affected by a Stack Based Overflow in the gray_split_cubic function of their custom fork of the rlottie library.

| Telegram Android <7.1.0 (2090), Telegram iOS <7.1, and Telegram macOS <7.1 are affected by a Heap Buffer Overflow in the VGradientCache::generateGradientColorTable function of their custom fork of the rlottie library.
