What happened

Filecoin Pin is an IPFS Pinning Service API implementation that pins to Filecoin's PDP service. Prior to 1.1.0, the upload GitHub Action's fork detection in upload-action/src/build.js checks only event.pull_request. In the documented two-workflow pattern, an untrusted fork pull-request workflow produces an artifact and a privileged workflow_run workflow downloads and uploads it. Because workflow_run has no event.

pull_request, isForkPR becomes false and uploadStatus becomes pending-upload. The action later resolves workflow_run.pull_requests without repeating the fork check before initializing the wallet with walletPrivateKey and uploading the artifact.

An external contributor can therefore cause attacker-controlled artifacts to be stored using the repository owner's Filecoin wallet, incurring unauthorized storage expenditure, dataset pollution and consumption of configured wallet funds. Disclosure of the wallet private key is not required. The 0.x action line is not receiving a backport and must be migrated to a fixed 1.x release. This issue is fixed in version 1.

1.0.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 22:30 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
