Hi,
The following vulnerability was published for epiphany-browser.
CVE-2026-118598[0]:
| A logic error in Epiphany's site permission handling can cause
| camera and microphone access to be granted when the user only
| approves a different permission. 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:
