CVE-2026-114089

Trigger.dev before 4.5.2 contains a cross-site request forgery vulnerability in the CLI authorization-code flow because loading /account/authorization-code/ mints a Personal Access Token without any consent step. Attackers mint an unauthenticated code, lure a logged-in user to that URL, then retrieve the victim's PAT from the unauthenticated /api/v1/token endpoint to take over the account.

CVE-2026-114107

HKUDS Vibe-Trading from 0.1.0 before 0.1.7 contains an indirect prompt injection vulnerability that allows remote attackers to execute shell commands as root by planting instructions in documents or web pages the agent processes. BashTool and BackgroundRunTool pass model-emitted commands to subprocess.run with shell=True and no allow-list or approval step, and read_url fetches arbitrary URLs, enabling command execution and server-side request forgery.

CVE-2026-114108

HKUDS Vibe-Trading from 0.1.0 before 0.1.7 contains a missing authentication vulnerability that allows unauthenticated attackers to access the FastAPI surface because require_auth() returns early when API_AUTH_KEY is unset. Attackers can post messages to /sessions/{id}/messages to trigger root shell commands via BashTool, upload .py or .sh files via /upload, read session histories, and obtain partial API keys.
