CVE-2026-12822 Details
Description
A vulnerability was identified in langflow-ai langflow up to 1.9.3. This affects an unknown function of the component Bundle URL Loader. The manipulation leads to code injection. The attack needs to be performed locally. The vendor was contacted early about this disclosure but did not respond in any way.
A code injection vulnerability has been identified in Langflow versions through 1.9.3. The issue arises from the Bundle URL Loader component, which improperly handles remote custom components. This vulnerability allows for arbitrary code execution, but requires local exploitation.
Users are advised not to auto-import remote custom component code. Instead, require explicit trust approval, signatures, or allowlists for such components. Consider sandboxing component loading and disabling remote bundle URLs by default in production environments.
