CVE-2026-0772

7.5

Langflow · Langflow

A deserialization vulnerability in the Langflow disk cache service allows authenticated remote attackers to execute arbitrary code on the host system.

Executive summary

A high-severity remote code execution vulnerability in Langflow, specifically within the disk cache component, poses a significant risk to system integrity and requires immediate attention.

Vulnerability

The vulnerability is a deserialization of untrusted data (CWE-502) occurring within the disk cache service. An attacker with valid credentials can exploit this flaw by supplying malicious data that the application fails to validate, leading to arbitrary code execution under the service account context.

Business impact

Successful exploitation of this vulnerability allows an attacker to achieve remote code execution, which could lead to full system compromise, data theft, or service disruption. Given the CVSS score of 7.5, this represents a high risk to business operations, particularly if the affected Langflow instance handles sensitive data or resides within a critical production environment.

Remediation

Immediate Action: Monitor official vendor channels and the Zero Day Initiative advisory for the release of a security patch and apply it as soon as it becomes available.

Proactive Monitoring: Review application access logs for suspicious activity originating from authenticated accounts and monitor the disk cache service for unexpected spikes in resource usage or file modifications.

Compensating Controls: Restrict access to the affected Langflow service to trusted networks only and ensure that the service account running the application operates with the principle of least privilege to limit the potential impact of code execution.

Exploitation status

Public Exploit Available: Unknown.

Analyst recommendation

Organizations utilizing Langflow should prioritize this issue within their vulnerability management lifecycle. While the requirement for authentication acts as a deterrent, the potential for total system compromise necessitates strict adherence to patch management once a fix is provided by the vendor. Continue to monitor the referenced Zero Day Initiative advisory for updates regarding remediation availability.
