CVE-2023-53951
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 · uneditedEver Gauzy v0.281.9 contains a JWT authentication vulnerability that allows attackers to exploit weak HMAC secret key implementation. Attackers can leverage the exposed JWT token to authenticate and gain unauthorized access with administrative permissions.
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 · moderate confidenceJWT authentication vulnerability in Ever Gauzy v0.281.9 stemming from weak HMAC secret key implementation. Attackers can forge JWT tokens using the exposed weak secret to bypass authentication and gain unauthorized administrative access.

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 Ever Gauzy installationSearch for Ever Gauzy directories or running processes (e.g., look for 'gauzy', 'gauzy-api', or related process names using 'ps aux | grep -i gauzy' or file system scans for gauzy-related folders)Affected if Ever Gauzy software is found running or installed on the system
-
Determine installed Ever Gauzy versionCheck the package.json file, docker-compose.yml, or version file within the Gauzy installation directory for the version number; compare it against the affected version v0.281.9 and nearby releasesAffected if Installed version matches or falls within the v0.281.9 release line (e.g., v0.281.x, v0.282.x)
-
Locate JWT configurationSearch for configuration files containing JWT settings: look for files named 'jwt.config.js', 'auth.config.js', 'config.ts', 'config.json', or similar in the Gauzy backend/api directory; also check for JWT-related entries in any configuration fileAffected if JWT configuration files exist and the application uses JWT for authentication
-
Inspect JWT secret keyOpen the JWT configuration files or environment configuration and examine the value assigned to JWT_SECRET, JWT_SECRET_KEY, or similar secret key variables; verify if the secret appears hardcoded, weak, or matches known default/placeholder valuesAffected if The JWT secret is hardcoded, set to a weak value, uses a default/placeholder string, or is absent (relying on a default)
-
Check environment variable configurationExamine .env files, container environment settings, or system environment variables for JWT-related secrets (e.g., JWT_SECRET, GAUZY_JWT_SECRET, SECRET_KEY); note whether the secret is loaded from a secure secrets manager or environment variableAffected if JWT secrets are stored insecurely (e.g., in version control, unencrypted config files) or use a weak/guessable key
A user is affected if Ever Gauzy v0.281.9 (or nearby versions) is running with JWT authentication enabled and the HMAC secret key is hardcoded, weak, or uses a default value.
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.
From vendor dataImmediately rotate the weak JWT HMAC secret to a cryptographically strong, randomly generated key; audit and update token generation/validation code to use secure key management; consider invalidating all existing sessions tokens.
