Lifecycle timeline
Electrum created
Product: Electrum
Thomas Voegtlin created Electrum in 2011; the project has remained in continuous development as a lightweight Bitcoin wallet.
Electrum 4.7.2 released with plugin security fixes
Product: Electrum
Electrum 4.7.2 was released with fixes for the external-plugin authorization bypass and the Nostr Wallet Connect daily spending-limit bypass later documented in the project security advisories.
External plugin authorization bypass disclosed
Product: Electrum
Electrum disclosed an external-plugin authorization bypass that could allow a rogue local process with filesystem write access to the Electrum data directory to execute arbitrary plugin code inside Electrum. The official advisory states the external-plugin system was affected from Electrum 4.6.0 until the fix in 4.7.2.
Nostr Wallet Connect spending-limit bypass disclosed
Product: Electrum
Electrum disclosed two flaws in its Nostr Wallet Connect plugin that could let a malicious or compromised NWC client spend above the configured daily limit through concurrent budget checks and millisatoshi truncation. The official advisory states the NWC plugin was affected from Electrum 4.6.0 until the fix in 4.7.2.
