DataBuff ai-apm-web through 0.1.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge admin session tokens by using the hardcoded HMAC secret in JwtTokenService. Attackers can sign a payload of admin and a future expiry with the default dev-secret to gain full administrative access to protected /webapi routes, including the Doris SQL query API.
