CVE-2026-54673

A flaw was found in electron-updater, a component used for automatic updates in Electron applications. This vulnerability allows a remote attacker to obtain sensitive user credentials. When an Electron application performs an HTTP redirect, the electron-updater's redirect handler fails to strip...

CVE-2026-54672

A flaw was found in electron-updater, a component used for automatic updates in Electron applications. This vulnerability arises because AppImage targets, built by app-builder-lib, incorrectly add the current working directory to the dynamic linker search path when setting the LDLIBRARYPATH...

CVE-2026-54673

electron-updater allows for automatic updates for Electron apps. Prior to 9.7.0, the HTTP redirect handler HttpExecutor.prepareRedirectUrlOptions only stripped a credential header whose key string matched exactly lowercase "authorization", exposing credentials. Other credential-bearing headers —...

CVE-2026-54672

electron-updater allows for automatic updates for Electron apps. Prior to 26.15.0, AppImage targets built by app-builder-lib could use an empty path component when setting the LDLIBRARYPATH environment variable at runtime. This causes the current working directory to be added to the dynamic linke...
