Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for llama-index-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update llama-index-core to 0.10.38 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fxc2-8m62-m85x 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.
