Security readout for executives and security teams

Plain-English summary

Electrum Bitcoin Wallet before 3.0.5 had a missing authorization flaw in its JSON-RPC interface. A malicious web page could abuse this path and steal bitcoin when the user’s wallet was not password protected. The CVE source says the issue was fixed in 3.0.5.

Executive priority

Prioritize remediation if the organization or key users used Electrum to hold bitcoin. The business risk is direct asset theft, not just system compromise. Legacy installations should be upgraded or removed immediately.

Technical view

The vulnerability is described as missing authorization in Electrum’s JSON-RPC interface before version 3.0.5. The stated attack path requires the victim to visit a web page containing specially crafted JavaScript. Impact is bitcoin theft, specifically noted when the wallet lacks password protection.

Likely exposure

Exposure is limited to users running Electrum Bitcoin Wallet versions earlier than 3.0.5, especially wallets without password protection. Organizations should focus on endpoints or users that held bitcoin wallets during the affected period.

Exploitation context

The bundle does not include KEV listing or confirmed active exploitation. The CVE description says exploitation requires a victim to visit a malicious web page, and theft is tied to wallets without password protection.

Researcher notes

Evidence is concise but clear: affected range is prior to 3.0.5, component is JSON-RPC, weakness is missing authorization, and the stated trigger is browser-delivered JavaScript. No CVSS, CWE, or KEV evidence is provided in the bundle.

Mitigation direction

  • Upgrade Electrum Bitcoin Wallet to version 3.0.5 or later.
  • Ensure Electrum wallets are password protected.
  • Check current Electrum vendor guidance for any newer security recommendations.
  • Treat exposed, unprotected wallets as potentially compromised and rotate funds appropriately.

Validation and detection

  • Inventory endpoints for Electrum installations and installed versions.
  • Confirm no Electrum version earlier than 3.0.5 remains in use.
  • Verify wallet password protection status where operationally possible.
  • Review relevant wallet transaction history for unauthorized bitcoin movement.
