Security Bulletin
Summary
Langflow OSS versions <= 1.9.3 contain SSRF vulnerability in legacy RSS Reader and SearXNG components that bypass SSRF protection introduced in v1.9.3. RSSReaderComponent calls requests.get(self.rss_url) directly on user input without validate_url_for_ssrf() check, completely bypassing protection layer. Component remains functional despite legacy=True marking and is invocable via JSON flow API. rss_url declared with tool_mode=True enables LLM agents to invoke as tool, creating prompt-injection-to-SSRF chain. Any authenticated user can exploit via single API call to: (1) exfiltrate cloud IMDS credentials (AWS/Azure/GCP IAM tokens) returned in component output enabling cloud account pivot; (2) enumerate internal networks; (3) bypass v1.9.3 security guarantee; (4) trigger SSRF via agent prompt injection. Requires only standard user authentication, no victim interaction. Exists in default configuration (ssrf_protection_enabled=True).
Vulnerability Details
CVEID: CVE-2026-10564
DESCRIPTION: Langflow OSS contains a Server-Side Request Forgery (SSRF). The legacy RSSReaderComponent in rss.py and SearXNG component in searxng.py make unvalidated HTTP requests to user-controlled URLs, bypassing SSRF protections introduced in version 1.9.3. An authenticated attacker can exploit this to access internal resources including cloud metadata services (AWS/Azure/GCP IMDS), potentially exfiltrating IAM credentials and enumerating internal networks. The vulnerability can also be triggered through prompt injection in agentic workflows due to tool_mode=True exposure.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
