CVE-2026-58170

Description

Vibe-Trading before 0.1.10 builds the proposal file path by joining a caller-supplied proposal identifier onto the broker proposals directory without sanitization (agent/src/live/mandate/commit.py). A proposal identifier containing path traversal sequences causes the application to load an attacker-controlled JSON file as an authoritative live trading mandate. Combined with the file upload endpoint, an admitted caller can write a JSON file to a known location and traverse to it, and because the ceilings validation is skipped when ceilings are absent, the attacker fully controls the committed mandate.
