Vulnerability in Aja Video Systems Helo Plus
CVE-2026-47097
AJA HELO Plus firmware before 2.1.7 contains an information disclosure vulnerability that allows unauthenticated attackers to decrypt sensitive diagnostics bundles by exploiting a static AES passphrase embedded in obfuscated form within the firmware. Attackers can reverse engineer the publicly available firmware image to recover the shared passphrase and decrypt diagnostics export bundles retrieved from the unauthenticated diagnostics endpoint on any affected device, exposing highly sensitive server information.
