Ledger Fixed a Critical Ethereum Wallet Flaw — But Kept Quiet About It for Two Weeks

Key Takeaway If your business holds or manages cryptocurrency, ensure all wallet software and firmware is kept fully up to date and monitor vendor security advisories closely.

Ledger, a well-known maker of hardware cryptocurrency wallets, quietly released a security update on August 12, 2026, to fix a critical vulnerability in its Ethereum wallet application. The fix was included in Ethereum app version 1.22.2, but the company did not publicly disclose details of the flaw for nearly two weeks after the patch went live.

Hardware wallets are designed to be one of the safest ways to store cryptocurrency, since private keys never leave the device. A critical vulnerability in the wallet software could potentially put users' funds at risk if exploited before a fix is applied, which is why timely patching and clear communication matter.

While Ledger has resolved the issue, the delay in public disclosure highlights a broader challenge in the security world: companies must balance quietly fixing problems before attackers notice them against keeping users informed so they can protect themselves.
