Token theft via caller-controlled management request destination
Published Aug 19, 2026 · Updated Aug 20, 2026
SSRF in Splunk Cisco Talos Intelligence for Enterprise Security Cloud before 1.0.3 allows remote authenticated users to expose tokens. The Talos intelligence enrichment REST endpoint accepts a destination for authenticated Splunk management requests directly from request data and sends the request there. A role with get_talos_enrichment is required; a crafted destination redirects tokens to an attacker-controlled server, compromising relevant Splunk data and system integrity.
