    CVE-2026-86115

    Published: 5 Sept 2026Last Modified: 25 Sept 2026

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

    Details: 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.
