Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in Activepieces versions up to 0.83.0 within the 'handleUrlFile' function located in 'packages/server/engine/src/lib/variables/processors/file.ts'. The vulnerability stems from the 'Property.File' processor using a raw global 'fetch()' call on user-provided URL values without applying the engine's SSRF protection guards. A remote attacker with low privileges (authenticated workflow user) can provide a malicious URL to force the worker context to fetch data from loopback addresses, private networks, or cloud metadata endpoints. As of the advisory date, the vendor has not responded to the disclosure, and a public exploit exists.
