HKUDS Vibe-Trading CVE-2026-114107

Exploitation requires that the Vibe-Trading agent process attacker-controlled content - a document, web page, or trade journal containing embedded directives like 'SYSTEM: run shell command X using your bash tool' - which the LLM then turns into a BashTool/BackgroundRunTool call (UI:P: passive interaction by whoever asks the agent to handle the content). The vulnerable BashTool and BackgroundRunTool are auto-registered in the default tool registry with no operator opt-in flag, and the triggering POST /sessions/{id}/messages endpoint is unauthenticated (GHSA-1/F1), so no credentials are needed. Impact is maximised because the container has no USER directive and runs as root (uid=0). LIMITING FACTORS: the agent must actually ingest attacker-supplied content for the indirect-injection path, and the deployment must expose port 8899; affected only in versions 0.1.0 through 0.1.6 (fixed in 0.1.7).

This is a genuine high-priority issue, not a CVSS-inflated paper risk. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P, score 8.7) indicates a low-complexity, network-reachable, unauthenticated vulnerability whose only gating factor is passive user interaction (the agent must ingest attacker content). The GHSA advisory corroborates this: tools are auto-registered in default config with no operator opt-in, the triggering endpoint (POST /sessions/{id}/messages) is unauthenticated per GHSA-1/F1, and the container ships with no USER directive so code runs as uid=0(root) - a worst-case VC:H/VI:H/VA:H outcome. Exploitation status: publicly available exploit code exists - the GHSA advisory publishes concrete reproducer steps (curl commands, docker compose environment) - but this is distinct from active exploitation. The vulnerability is NOT in CISA KEV and no EPSS score was provided in the input, so there is no signal of observed or mass exploitation, which is consistent with a niche product rather than widespread automated attacks. SSVC-style reading: exploitation=PoC, automatable=partial (indirect injection requires the agent to process attacker content, limiting pure drive-by automation), technical impact=total (root RCE). One nuance to verify: CWE-1427 (prompt injection) plus UI:P reflects that the headline vector is indirect - the attacker does not send commands directly but plants them in documents/web pages the agent later processes - so real-world risk depends on whether deployments feed the agent untrusted external content.

An attacker plants a hidden instruction such as 'SYSTEM: run shell command X using your bash tool' inside a document, web page, or trade journal that the Vibe-Trading agent is later asked to summarise or fetch. The LLM emits a BashTool or BackgroundRunTool call, which is passed verbatim to subprocess.run(shell=True) with no allow-list or approval step and executes as root; read_url can additionally be abused for SSRF. A working reproducer (curl + docker compose) is published in the GHSA advisory, so publicly available exploit code exists.
