Vulnerability Snapshot
CVE-2026-9813 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.
Affected technology: flowintel.
Executive Summary
FlowIntel up to version 3.3.0Â contains a server-side request forgery (SSRF) vulnerability in the external reference URL probe functionality in app/case/task.py. An attacker who can submit an external reference URL can cause the application server to issue an HTTP HEAD request to an attacker-specified destination. Due to insufficient validation of the URL scheme and resolved destination address, affected versions may allow requests to loopback, link-local, private, reserved, or other restricted network resources, potentially enabling interaction with internal services or cloud metadata endpoints from the server's network context.
Why It Matters
CVE-2026-9813 is rated CRITICAL severity, requiring immediate attention from security teams.
CVSS Base Score: 9.9/10
EPSS (Exploit Prediction): 0.0% probability of exploitation in the next 30 days.

Vendors: flowintel

Frequently Asked Questions
What is CVE-2026-9813?
CVE-2026-9813 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. FlowIntel up to version 3.3.0Â contains a server-side request forgery (SSRF) vulnerability in the external reference URL probe functionality in app/case/task.py. An attacker who can submit an external
Am I affected?
Check whether your environment runs flowintel. If you operate any of those, treat yourself as in scope until you have evidence otherwise. A Vulnios scan will identify the exact assets carrying the affected version.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2026-9813. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch.
