    UBUNTU-CVE-2019-11748

    Published: 4 Sept 2019Last Modified: 22 Apr 2026
    Upstream:
    CVE-2019-11748
    Aliases:
    USN-4122-1

    Summary:

    Details: WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
