CVE-2026-34779 | Electron: AppleScript injection in app.moveToApplicationsFolder on macOS

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8, on macOS, app.moveToApplicationsFolder() used an AppleScript fallback path that did not properly handle certain characters in the application bundle path. Under specific conditions, a crafted launch path could lead to arbitrary AppleScript execution when the user accepted the move-to-Applications prompt. Apps are only affected if they call app.moveToApplicationsFolder(). Apps that do not use this API are not affected. This issue has been patched in versions 38.8.6, 39.8.1, 40.8.0, and 41.0.0-beta.8.

Base score Version Severity Vector Exploitability Impact Score source
6.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.

Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
