CVE-2025-13804Public exploitNetwork attack vector

Wallet password disclosure via unfiltered account serialization

Published Dec 1, 2025 · Updated Feb 24, 2026

Information disclosure in NutzBoot 2.6.0-SNAPSHOT allows remote attackers to read Ethereum wallet passwords through an unauthenticated endpoint. EthModule.localeAccounts returns the web3jCredentials map as JSON while its output filter excludes credentials but leaves Web3jAccount.password serializable. Exposure requires the Web3j demo module, at least one configured local account, and network access to the route; disclosed passwords can unlock associated keystores.
