CVE-2026-76440

Unspecified impact via path traversal

Published Sep 14, 2026 · Updated Sep 14, 2026

Path traversal in Cisco Secure Email and Cisco Secure Email and Web Manager allows attackers to cause unspecified impact via unspecified vectors. Cisco has not published the affected component or the operation that fails to constrain an externally influenced path to its intended directory. The required access, reachable interface, and resulting file operation or other consequence remain undisclosed, so impact cannot be bounded beyond the source record.
