Transitive Vulnerabilities Exploit In Real-life
summary
Claim: open‑source vulnerabilities in JavaScript are mostly transitive, and exploitability falls as dependency depth increases. A dependency‑graph + import/usage analysis runs over thousands of repositories and auto‑triages; LLMs (e.g. OpenAI and Llama 3) validate direct cases where a short PoC crashes a pars‑server instance. For transitive risk a statistical formula uses an Alpha scaling factor with CWE‑based exploitability scores to produce a 0–1 prioritization metric for remediation.
