Any authenticated Payload user can obtain a cryptographically valid Cloudinary HMAC-SHA1 signature for arbitrary upload parameters — including `overwrite=true`, `type=private`, `notification_url`, and path-traversal folder values — enabling unauthorized asset replacement, access-control bypass, and potential SSRF within the configured Cloudinary account.\n\n### Details\n\nWhen `clientUploads: true` is configured, the plugin registers a signing handler at `cloudinary/src/index.ts:74-79`. The handler is implemented in `cloudinary/src/getGenerateSignature.ts`.\n\n**Vulnerable code path (step by step):**\n\n1. `cloudinary/src/index.ts:58` — `initClientUploads` registers the server upload handler.\n2. `cloudinary/src/index.ts:68` — The Cloudinary API key is exposed to client handler props by design.\n3. `cloudina","public_affected_ranges":[">= 0.3.0, < 0.4.0"]}],"null_published_at":"2026-11-05T19:10:21.467Z","source_updated_at":"2026-06-23T05:02:33.000Z","source_disclosed_at":"2026-06-19T22:10:37.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-05T19:06:16.668Z"}],"next_cursor":null,"snapshot_revision":"42594"}
