Vulnerability Title
openssl_encrypt before 1.4.9 Key Substitution via Identity Load
Source: CVE Program / CVE List V5
Vulnerability Description
openssl_encrypt before 1.4.9 fails to re-derive and validate fingerprints when loading identities from identity.json, allowing attackers to substitute public keys in identity stores. Attackers can replace legitimate public keys with their own while maintaining the claimed fingerprint, enabling silent key substitution where encryption uses attacker keys and signature verification appears valid.
