Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to versions 3.3.3, 3.4.6, and 3.5.3, when ssl is enabled without a pinned CA or server certificate, MariaDB Connector/Node.js sends credentials before completing certificate fingerprint validation. In lib/cmd/handshake/auth/handshake.js, a server that selects mysql_clear_password as the initial authentication plugin can receive the password before the post-TLS identity check. In lib/cmd/handshake/authentication.js, an authentication switch can evaluate the previous plugin instead of the requested target plugin, allowing mysql_clear_password to send the credential first. An active man-in-the-middle can present a self-signed certificate, capture the database password, and use it to authenticate directly even though the connector later rejects the server and closes the connection. This issue is fixed in versions 3.3.3, 3.4.6, and 3.5.3.

---METADATA---
VENDOR: Langflow
PRODUCT: Langflow
AFFECTED_VERSIONS: Prior to 1.9.2
---END_METADATA---
Description Summary:
A path traversal vulnerability in Langflow components based on BaseFileComponent allows attackers to read arbitrary files from the server's filesystem via manipulated RAG input files.
Executive Summary:
Langflow versions prior to 1.9.2 are vulnerable to arbitrary file read attacks, allowing unauthorized access to sensitive system files via malicious RAG components.
Vulnerability Details
CVE-ID: CVE-2026-55447
Affected Software: Langflow Langflow
Affected Versions: Prior to 1.9.2
Vulnerability: The vulnerability affects multiple RAG-related components, such as Docling and various file readers. By providing a malicious path within an input file, an attacker can trick the system into reading sensitive files from the server's filesystem using an absolute path.
Business Impact
This vulnerability could result in the total disclosure of sensitive configuration files, environment variables, or system credentials stored on the application server. With a CVSS score of 9.6, the potential for full system compromise via credential harvesting or configuration exposure is severe.
Remediation Plan
Immediate Action: Update Langflow to version 1.9.2 or later to apply the necessary filesystem access restrictions.
Proactive Monitoring: Monitor filesystem access logs for unexpected read attempts outside of intended directories and audit the contents of uploaded RAG data.
Compensating Controls: Ensure the Langflow application is running within a containerized environment with minimal filesystem privileges to limit the impact of potential traversal attacks.
Exploitation Status
Public Exploit Available: Unknown
Analyst Notes: As of Jun 23, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
The risk of arbitrary file reading requires immediate attention to protect sensitive system data. Administrators should deploy version 1.9.2 and conduct a thorough audit of any previously processed RAG data to ensure no compromise has already occurred.
