Description
Impact
Ballcat Codegen provides the function of online editing code to generate templates. In version < 1.0.0.beta.2, since Velocity and freemarker templates are introduced but input verification is not done, attackers can implement remote code execution through malicious code injection of the template engine.
Patches
The fault is rectified and needs to be upgraded to the latest version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.hccake:ballcat-codegen, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.hccake:ballcat-codegen to 1.0.0.beta.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24881 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
