{"schemaVersion":3,"id":"CVE-2026-76390","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Cisco Talos Intelligence for Enterprise Security Cloud versions below 1.0.3, an unauthenticated user could access the add-on OpenAPI specification through Splunk Web static file paths. The exposed specification could allow for reconnaissance of the add-on Representational State Transfer (REST) API endpoints and authentication model. The vulnerability is possible because the generated OpenAPI specification is packaged in a static file path that Splunk Web serves without authentication.

(https://help.splunk.com/en/splunk-enterprise-security-8/user-guide/8.0/introduction/deploy-cisco-talos-intelligence-for-splunk-enterprise-security-cloud-only) in the Splunk
