Description

Impact

If you are using the esbuild target or command you are at risk of code/option injection. Attackers can use the command line option to maliciously change your settings in order to damage your project.

Patches

The problem has been patched in v1.0.0 as it uses a proper method to pass configs to esbuild/estrella.

Workarounds

There is no work around. You should update asap.

Notes

This notice is mainly just to make sure people update to the latest version. This isn't that bad, but should encourage you to update.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @floffah/build, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update @floffah/build to 1.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jcgr-9698-82jx is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
