Prior to 0.17.1, ScriptExecution.correctlySpends() contains two fast-path verification bugs for standard P2PKH and native P2WPKH spends in core/src/main/java/org/bitcoinj/script/ScriptExecution.java. In both branches, bitcoinj verifies an attacker-controlled signature/public-key pair but fails to verify that the public key is the one committed to by the output being spent. As a result, any attacker keypair can satisfy bitcoinj's local verification for arbitrary P2PKH and P2WPKH outputs. This vulnerability is fixed in 0.17.1."}], "lastModified": "2026-05-18T19:59:59.590", "sourceIdentifier": "security-advisories@github.com"}
