CVE-2023-48396
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWeb Authentication vulnerability in Apache SeaTunnel. Since the jwt key is hardcoded in the application, an attacker can forge any token to log in any user. Attacker can get secret key in /seatunnel-server/seatunnel-app/src/main/resources/application.yml and then create a token. This issue affects Apache SeaTunnel: 1.0.0. Users are recommended to upgrade to version 1.0.1, which fixes the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceApache SeaTunnel 1.0.0 uses a hardcoded JWT secret key stored in the application.yml configuration file. An attacker who obtains this key can forge authentication tokens and impersonate any user, gaining unauthorized access to the system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed SeaTunnel versionCheck the SeaTunnel installation directory for version information, typically found in a version file, pom.xml, or release notes. If running via package manager, use: seatunnel --version or check the JAR manifest.Affected if Version is exactly 1.0.0
-
Locate the application.yml configuration fileFind the application.yml file in the SeaTunnel configuration directory. Common paths include: config/application.yml, conf/application.yml, or in the classpath under resources/.Affected if The application.yml file exists and contains JWT-related configuration
-
Check if web authentication module is enabledIn application.yml, look for sections under seatunnel:web or similar web-related configuration. Check for authentication settings or security configurations.Affected if Web authentication module is enabled and configured in application.yml
-
Inspect JWT secret key configurationIn application.yml, locate the jwt:secret or security:jwt:secret configuration key. Examine whether a static, hardcoded string value is present rather than an empty/null value or environment variable reference.Affected if A non-empty, static string value is configured for the JWT secret (e.g., jwt: secret: "a-long-static-string")
You are affected if running SeaTunnel version 1.0.0 with web authentication enabled and a hardcoded JWT secret string exists in application.yml.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to Apache SeaTunnel 1.0.1 which replaces the hardcoded key with a dynamically generated or externalized secret. Additionally, invalidate and rotate all existing tokens after the upgrade.
1.0.1
- Upgrade Apache SeaTunnel from version 1.0.0 to version 1.0.1 to obtain the fixed JWT key implementation
