Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, requests to open external protocol URLs from web content did not take iframe sandbox restrictions into account, so a sandboxed iframe could cause an OS-registered external application to be launched. The frame sandbox state was also not made available to the app permission handlers, affecting apps that render untrusted content in sandboxed iframes and grant the openExternal permission by default when no setPermissionRequestHandler is installed. This issue is fixed in 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","score":5.4,"severity":null}],"references":["https://github.com/electron/electron/security/advisories/GHSA-p2rr-rvmm-c5fp","https://github.com/electron/electron/pull/50961","https://github.com/electron/electron/pull/50962","https://github.com/electron/electron/pull/50963","https://github.com/electron/electron/pull/50964","https://github.com/electron/electron/commit/08b9d0a220e267d1a2402a44bdd01a2e9aa320b5","https://github.com/electron/electron/commit/2764e4c35168855f614876051823db4f58a3714a","https://github.com/electron/electron/commit/477dcf7afc6550715f9ec5e6f39ee38e5dd7bf39","https://github.com/electron/electron/commit/c39e3d5687d57434c8d5fe814c5152efd2f631c3","https://github.com/electron/electron/releases/tag/v39.8.8","https://github.com/electron/electron/releases/tag/v40.9.0","https://github.com/electron/electron/releases/tag/v41.2.1","https://github.com/electron/electron/releases/tag/v42.0.0-beta.3"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-53546","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 5, 2026, 5:56:41 PM","dateUpdated":"Aug 5, 2026, 7:03:29 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
