CVE-2026-86408 MISP Missing Authorization in Cryptographic Key View Exposes Signing Keys from Protected Events

Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view. The vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as: type keydata fingerprint but did no...
