load() now enforces the same workspace-root boundary as file()/glob()/query() — a `..`-laden path that would resolve outside the workspace is rejected instead of being followed. Ref: hephbuild/heph@66dea21 (#277)

There was a problem hiding this comment.
My mistake — I pre-base64-encoded the file content before sending it through the file-update API, which already does that encoding itself, so the first commit landed the literal base64 string as the file body instead of the markdown. Fixed in 8c9ba0b: the diff is now just the intended one-paragraph addition to the load() section. Sorry for the noise.

The prior commit sent the file content pre-base64-encoded, but this tool already base64-encodes the `content` param — so the committed file literally contained the base64 string instead of the markdown.

Summary
hephbuild/heph#277(commit66dea21) closed a security bug whereload()path resolution had no workspace-root boundary check, so a..-laden or//-absolute path (e.g.load("../../../../etc/hosts")) could escape the workspace and be parsed as Starlark.load()now enforces the same boundary check asfile()/glob()/query(), rejecting such paths with an error.website/docs/plugins/buildfile.mdalready documented this workspace-root boundary forfile()/glob()/query()paths, but was silent onload(). Added one sentence to the "Sharing symbols withload()" section mirroring the existing statement, now thatload()behaves the same way.Not documented (out of scope, no user-facing docs claim to correct): the companion fix for package-address escapes (
Provider::get/list/probenow returning empty/not-found for a..-escaping package address) and thelist_packagessymlinked-BUILD-file fix — both are internal consistency fixes with no prior doc claims to update.Test plan
