Description

Both providers treated any non-URL image string as a local filesystem path, read it with fs.readFile, and uploaded the bytes to a third-party IPFS pinning service (web2-api.flaunch.gg and Pinata respectively), which pins them publicly. Because image is an LLM-supplied tool argument whose description explicitly advertised "Local image file path", an agent could be induced to read an arbitrary file off the host and publish it.

The local-file affordance is not useful to an agent, which has no knowledge of the host filesystem. It only ever served direct programmatic SDK callers, who can perform the read themselves.

  • flaunch: image accepts http(s):// URLs or data: URIs
  • zora: image accepts https:///ipfs:// URIs or data: URIs
  • Anything else is rejected before any file or network access
  • Zod schemas reject non-URL values, so the constraint is also visible to the model rather than surfacing only as a runtime error
  • Tool/schema descriptions and READMEs no longer advertise local paths

Callers publishing a local file now pass a data URI:

image: `data:image/png;base64,${fs.readFileSync(p, "base64")}`

Tests

Manually tested and verified

Checklist

A couple of things to include in your PR for completeness:

  • Added documentation to all relevant README.md files
  • Added a changelog entry

Per CONTRIBUTING-TYPESCRIPT.md, breaking changes take a minor bump.
Restricting `image` to remote URLs and data URIs breaks callers that
currently pass a local file path, so this is not a patch. Also added the
data URI migration snippet to the changeset so it lands in the published
changelog rather than only in the PR description.

Description

Both providers treated any non-URL image string as a local filesystem path, read it with fs.readFile, and uploaded the bytes to a third-party IPFS pinning service (web2-api.flaunch.gg and Pinata respectively), which pins them publicly. Because image is an LLM-supplied tool argument whose description explicitly advertised "Local image file path", an agent could be induced to read an arbitrary file off the host and publish it.

The local-file affordance is not useful to an agent, which has no knowledge of the host filesystem. It only ever served direct programmatic SDK callers, who can perform the read themselves.

  • flaunch: image accepts http(s):// URLs or data: URIs
  • zora: image accepts https:///ipfs:// URIs or data: URIs
  • Anything else is rejected before any file or network access
  • Zod schemas reject non-URL values, so the constraint is also visible to the model rather than surfacing only as a runtime error
  • Tool/schema descriptions and READMEs no longer advertise local paths

Callers publishing a local file now pass a data URI:

image: `data:image/png;base64,${fs.readFileSync(p, "base64")}`

Tests

Manually tested and verified

Checklist

A couple of things to include in your PR for completeness:

  • Added documentation to all relevant README.md files
  • Added a changelog entry

Restricting `image` to remote URLs and data URIs breaks callers that
