When dragging content from the primary browser pane to the addressbar on a malicious site, it is possible to change the addressbar so that the displayed location following navigation does not match the URL of the newly loaded page. This allows for spoofing attacks. This vulnerability affects Firefox < 52.

Security readout for executives and security teams

A malicious site could make Firefox show a misleading address after navigation, so users may believe they are on a trusted site when they are not. The source bundle says this affects Firefox before version 52. Business risk is mainly credential theft or fraud through convincing browser spoofing on legacy endpoints. Exposure is limited to systems still running Mozilla Firefox before version 52. Modern managed browsers are unlikely to be exposed if patching is current. Highest concern is unmanaged legacy desktops, kiosks, lab machines, or embedded workflows using old Firefox builds. Treat as a legacy-browser exposure issue. Prioritize remediation where old Firefox remains available to users handling credentials, payments, customer data, or administrative portals. Mitigation focus: Upgrade Firefox to version 52 or later, preferably a current supported release.; Inventory endpoints for Firefox versions older than 52.; Retire legacy browser use on shared, kiosk, or unmanaged systems..
