Detailsinfo

A vulnerability was found in jahlives openssl_encrypt up to 1.4.8. It has been declared as critical. This vulnerability affects the function openssl_encrypt of the file identity.json. The manipulation with an unknown input leads to a signature verification vulnerability. The CWE definition for the vulnerability is CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-81702 since 08/27/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.
