CVE-2022-24881: Ballcat Codegen

Critical severity, CVSS 9.8. EPSS: 3.2% chance of exploitation in the next 30 days.

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 Codegen: before 1.0.0 (fixed in 1.0.0)
