CVE-2026-85669Network attack vectorHinoki check available

Cross-user file modification via missing ownership check

Published Sep 4, 2026 · Updated Sep 4, 2026

Missing authorization in Potpie 2.0.0 and earlier allows remote authenticated users to modify other users' pending code changes. The POST /conversations/{conversation_id}/code-changes/sync endpoint accepts a caller-supplied conversation ID and synchronizes file changes without confirming that the caller owns the conversation. Any authenticated account with another conversation ID can overwrite its pending changes, while confidentiality and availability remain unaffected.
