Prior to 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5, windows opened from a sandboxed top-level document did not inherit that document's active HTML sandbox restrictions. Untrusted content in a sandboxed top-level document that was permitted to open popups could therefore create a window with the Electron application's full origin instead of the restricted origin intended by the sandbox. Applications that deny such popups with setWindowOpenHandler are not affected. This issue is fixed in versions 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2,"severity":null}],"references":["https://github.com/electron/electron/security/advisories/GHSA-gr2m-v5gq-v685","https://github.com/electron/electron/commit/29fc130569f970e91e355383821a4af0f25724a2","https://github.com/electron/electron/commit/3ecf3e74f4be6e2360644679b0b4698742be0e1d","https://github.com/electron/electron/commit/6594d5a5b074cf501da084dc7908d3df0d68a886","https://github.com/electron/electron/commit/e9c4d3cbe912e18d7c63af78e63e98ae7a48cd3a","https://github.com/electron/electron/releases/tag/v41.10.6","https://github.com/electron/electron/releases/tag/v42.9.2","https://github.com/electron/electron/releases/tag/v43.4.1","https://github.com/electron/electron/releases/tag/v44.0.0-beta.5"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-89091","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 29, 2026, 4:51:26 PM","dateUpdated":"Sep 29, 2026, 5:20:35 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
