In src/ephy-window.c, set_permission() stores the user's Allow/Deny choice after a WebKit permission dialog. Types CLIPBOARD and WEBSITE_DATA_ACCESS are not stored by ephy_permission_is_stored_by_permissions_manager(), so control fell into an else-if that was written as:
} else if (EPHY_PERMISSION_TYPE_ACCESS_WEBCAM_AND_MICROPHONE) {
Because that expression is a non-zero enum constant, the branch always ran for those types and wrote EPHY_PERMISSION_PERMIT for both ACCESS_WEBCAM and ACCESS_MICROPHONE for the site origin. The user only saw a Clipboard or Website Data Access dialog.
A malicious site that obtains approval for clipboard or third-party storage access can afterwards use getUserMedia without a further camera/microphone prompt, exposing audiovisual confidentiality.
Requirements: the victim must visit a malicious page and click Allow on a clipboard or website-data-access prompt.
Affected: Epiphany >= 45.0 (bug present at least through 51.x).
Fixed: https://gitlab.gnome.org/GNOME/epiphany/-/merge_requests/2249 (commit 480c3648).
Upstream: https://gitlab.gnome.org/GNOME/epiphany/-/work_items/2976

Vendor Workaround
Do not approve Clipboard or Website Data Access prompts on untrusted sites. Review and revoke camera and microphone site permissions in Epiphany (site permissions / privacy settings) for any origin where those prompts were accepted. Prefer browsing untrusted content with media devices disconnected or disabled at the OS level. Upgrade to a fixed Epiphany build containing MR !2249 / commit 480c3648 when available for your stream.
