An attacker could exploit this vulnerability by sending a crafted request to the provisioning download service. A successful exploit could allow the attacker to access protected files without authentication, potentially exposing sensitive information.\n\n## Affected\n\n- `identity_services_engine >= 3.1.0, < 3.3.0`\n- `identity_services_engine = 3.3.0`\n- `identity_services_engine = 3.4.0`\n- `identity_services_engine = 3.5.0`\n- `identity_services_engine_passive_identity_connector >= 3.1.0, < 3.3.0`\n- `identity_services_engine_passive_identity_connector = 3.3.0`\n- `identity_services_engine_passive_identity_connector = 3.4.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `identity_services_engine 3.3.0`\n- `identity_services_engine_passive_identity_connector 3.3.0`\n\n## Vendor advisories\n\n- **cisco-sa-ise-multi-traversal-WDTgYCdn** · Cisco · affected: Cisco ISE Passive Identity Connector (4 versions), Cisco Identity Services Engine Software (47 versions) · updated 2026-09-16 · [advisory](https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-multi-traversal-WDTgYCdn)","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.3,"exploitation":0,"ransomware":0},"changes":[]}
