AJ-Report through 1.7.1 Authentication Bypass leading to RCE via Share-Token

Summary

AJ-Report through 1.7.1 signs share tokens with a hard-coded JWT secret, allowing attackers to forge valid Share-Tokens offline. Attackers can mint a token with reportCode 'dataSet' to access the testTransform endpoint, which passes scripts to GroovyClassLoader for unauthenticated remote code execution.

Remediation

1. Inventory every anji-plus AJ-Report deployment, including staging.
2. No fixed version appears in the public sources yet. Check the references below and the vendor directly.
