Sim before 0.8.14 Confused Deputy in Tool URL Routing Mints an Internal Token for a User-Supplied /api/ Path

Type: advisorySource: Official CVE List1 source record

Sim before 0.8.14 classifies tool requests as internal based on URL prefix matching without scheme normalization, skipping SSRF validation and minting internal authentication tokens. Authenticated workflow authors can bypass external URL validation by supplying paths starting with /api/ in HTTP blocks to reach internal-only endpoints like POST /api/function/execute.
