CVE-2026-70611

mediumCVSS 6.9covered by 1 sourcefirst seen 2026-08-05

Impact The DevTools "reveal in file manager" action could launch the target file rather than reveal it. An attacker with a separate means of running script inside the DevTools frontend (such as a malicious DevTools extension) could use this to execute native code outside the sandbox. Apps are only affected if DevTools is opened for windows exposed to untrusted content or untrusted DevTools extensions. Apps that do not open DevTools in that context are not affected. Workarounds Do not open DevTools for windows that load untrusted content, and do not load untrusted DevTools extensions. Fixed Versions - 42.0.0-beta.3 - 41.2.1 - 40.9.2 - 39.8.9 For more information If you have any questions or comments about this advisory, email Electron at security@electronjs.org
