ENS DNSSEC Oracle Vulnerable to RSA Signature Forgery via Missing PKCS#1 v1.5 Padding Validation

Impact The RSASHA256Algorithm and RSASHA1Algorithm contracts fail to validate PKCS1 v1.5 padding structure when verifying RSA signatures. The contracts only check if the last 32 or 20 bytes of the decrypted signature match the expected hash. This enables Bleichenbacher's 2006 signature forgery...

CVE-2026-22866

Ethereum Name Service ENS is a distributed, open, and extensible naming system based on the Ethereum blockchain. In versions 1.6.2 and prior, the RSASHA256Algorithm and RSASHA1Algorithm contracts fail to validate PKCS1 v1.5 padding structure when verifying RSA signatures. The contracts only check...

CVE-2026-22866

The CVE-2026-22866 entry describes a Bleichenbacher-style RSA signature forgery flaw in Ethereum Name Service (ENS) DNSSEC tooling. In ENS v1.6.2 and earlier, RSASHA256Algorithm and RSASHA1Algorithm do not validate PKCS#1 v1.5 padding correctly and only compare the trailing 32 (or 20) bytes of th...
