| CVE-2021-27229 | Mumble before 1.3.4 allows remote code execution if a victim navigates to a crafted URL on a server list and clicks on the Open Webpage text. | [email protected] | 8.8 | 3.20% | 2021-02-15 | 2026-06-16 |
| CVE-2020-13962 | Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users.

| CVE-2018-20743 | murmur in Mumble through 1.2.19 before 2018-08-31 mishandles multiple concurrent requests that are persisted in the database, which allows remote attackers to cause a denial of service (daemon hang or crash) via a message flood. | [email protected] | 7.5 | 3.62% | 2019-01-25 | 2026-06-16 |
| CVE-2014-3756 | The client in Mumble 1.2.x before 1.2.6 allows remote attackers to force the loading of an external file and cause a denial of service (hang and resource consumption) via a crafted string that is treated as rich-text by a Qt widget, as demonstrated by the (1) user or (2) channel name in a Qt dialog, (3) subject common name or (4) email address to the Certificate Wizard, or (5) server name in a tooltip. | [email protected] | 5.0 | 1.48% | 2014-11-16 | 2026-06-16 |
| CVE-2014-3755 | The QSvg module in Qt, as used in the Mumble client 1.2.x before 1.2.6, allows remote attackers to cause a denial of service (hang and resource consumption) via a local file reference in an (1) image tag or (2) XML stylesheet in an SVG file. | [email protected] | 5.0 | 2.52% | 2014-11-16 | 2026-06-16 |
| CVE-2012-0863 | Mumble 1.2.3 and earlier uses world-readable permissions for .local/share/data/Mumble/.mumble.sqlite files in home directories, which might allow local users to obtain a cleartext password and configuration data by reading a file. | [email protected] | 2.1 | 0.38% | 2012-04-30 | 2026-06-16 |
