Versions prior to 3.17.0 expose a deprecated public upload endpoint at `GET /api/v1/typebots/{typebotId}/blocks/{blockId}/storage/upload-url` that accepts an attacker-controlled `filePath` and returns a presigned S3 `PUT` URL for that exact key. Because the endpoint only checks that the referenced typebot is public and that the referenced block is a file input block, an unauthenticated attacker who knows a valid public `typebotId` and `blockId` can request presigned upload URLs for arbitrary objects in the shared bucket, including `private/...` and other tenants' `public/...` paths. Version 3.17.0 fixes this issue."}],"source":{"advisory":"GHSA-m7f5-3wcm-x2c4","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-m7f5-3wcm-x2c4","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-12T12:50:20.706540Z","id":"CVE-2026-48763","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-12T12:50:41.326Z"}}]}}
