- CVE-2026-102677
- CVSS_V3
- CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
Description
### Impact The cache Electron keeps for sandboxed preload scripts did not verify that a cached entry matched the preload it was served for. A compromised renderer could use this to run its own code in the preload context on a later load. Apps are only affected if they load untrusted content. Apps that do not load untrusted content are not affected. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `44.0.0-beta.6` * `43.5.0 ` * `42.10.0` ### For more information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)
