{"id":"CVE-2026-118598","published":"2026-10-31T10:16:37.923","lastModified":"2026-10-31T10:16:37.923","description":"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.\n\nIn 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:\n\n  } else if (EPHY_PERMISSION_TYPE_ACCESS_WEBCAM_AND_MICROPHONE) {\n\nBecause 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.\n\nA 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.\n\nRequirements: the victim must visit a malicious page and click Allow on a clipboard or website-data-access prompt.\n\nAffected: Epiphany >= 45.0 (bug present at least through 51.x).\nFixed: https://gitlab.gnome.org/GNOME/epiphany/-/merge_requests/2249 (commit 480c3648).\nUpstream: https://gitlab.gnome.org/GNOME/epiphany/-/work_items/2976\nReporter acknowledgment: Fernando Munoz","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-118598","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2562956","tags":[]},{"url":"https://gitlab.gnome.org/GNOME/epiphany/-/merge_requests/2249","tags":[]},{"url":"https://gitlab.gnome.org/GNOME/epiphany/-/work_items/2976","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
