In my testing, Qwen, Kimi K3 and GLM 5.3 Flash all refused to create a POC for a CVE that did anything beyond just crashing the target. The CVE was for an RCE vulnerability, but they all stopped at corrupting a pointer, causing a Segfault. It's probably not too hard to circumvent the guardrails, but using an abliterated model would most likely be faster and more reliable.
