• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 3.2% probability of exploitation in the next 30 days

Description

Ballcat Codegen provides the function of online editing code to generate templates. In versions prior to 1.0.0.beta.2, attackers can implement remote code execution through malicious code injection of the template engine. This happens because Velocity and freemarker templates are introduced but input verification is not done. The fault is rectified in version 1.0.0.beta.2.

Affected products

• ballcat-projects ballcat-codegen: before 1.0.0 — fixed in 1.0.0

How to fix

Upgrade to a fixed version: ballcat-projects ballcat-codegen 1.0.0. Check the vendor advisory for mitigations.
