Security readout for executives and security teams
CVE-2017-7759 affected Firefox for Android before version 54. A malicious Android intent URL could move a browser session from a normal web page to a local file URL, breaking same-origin protections and potentially allowing local data to be read. The issue is narrow because Mozilla states other operating systems were not affected. Exposure is most likely on Android devices running Firefox for Android earlier than version 54. Current managed fleets are unlikely to be exposed unless they retain very old browsers, unmanaged Android devices, or archived test environments. Treat this as a legacy mobile-browser exposure check, not an emergency. Prioritize confirmation if the organization manages Android devices, supports BYOD access, or keeps old Android test devices with historical Firefox builds. Mitigation focus: Upgrade Firefox for Android to version 54 or later.; Confirm Android devices do not run unsupported legacy Firefox versions.; Check Mozilla advisory MFSA 2017-15 for vendor-specific guidance..
