Security readout for executives and security teams
Plain-English summary
Langflow has a critical flaw that can let an unauthenticated remote attacker run code on the server. If Langflow 1.3.2 is exposed to untrusted networks, compromise could affect confidentiality, integrity, and availability. No provided source shows active exploitation.
Executive priority
Prioritize immediately for any internet-facing Langflow 1.3.2 system. The issue is unauthenticated remote code execution with critical impact, even though active exploitation is not evidenced in the provided sources.
Technical view
CVE-2026-0769 is a CWE-95 eval injection in Langflow’s eval_custom_component_code function. User-supplied input is not properly validated before being used to execute Python code, enabling code execution in the current process. CVSS is 9.8 with network access, low complexity, no privileges, and no user interaction.
Likely exposure
Highest concern is Langflow 1.3.2 reachable from the internet or other untrusted networks. The source bundle lists Langflow 1.3.2 and does not clearly define broader version exposure or a fixed version.
Exploitation context
The advisory describes unauthenticated remote code execution. CISA KEV status is false in the source bundle, and no cited source states active exploitation. Treat exposure as urgent due to trivial preconditions and full-impact CVSS scoring.
Researcher notes
Evidence is limited to CVE data and ZDI advisory details. The root issue is unsafe evaluation of user-controlled input in eval_custom_component_code. Do not assume affected versions beyond those listed without vendor confirmation.
Mitigation direction
- Identify and prioritize any Langflow 1.3.2 deployments.
- Check Langflow and ZDI guidance for fixed versions or vendor workarounds.
- Remove public exposure where possible until remediation is confirmed.
- Restrict access to trusted networks or controlled administrative paths.
- Monitor for unusual Langflow process activity and unexpected code execution indicators.
Validation and detection
- Inventory Langflow instances and confirm installed versions.
- Determine whether instances are reachable from internet or untrusted networks.
- Review access controls protecting Langflow administrative and workflow interfaces.
- Check vendor advisories for updated affected-version and fixed-version information.
- Review logs for unexpected custom component activity; no IOCs were provided.

Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')
Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
