Description

This security bulletin contains information about 1 vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-27023)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose sensitive information from internal network services.

The vulnerability exists due to server-side request forgery in SecureHttpClientService when following HTTP redirects for outbound requests. A remote user can supply a URL that redirects to an internal network address to disclose sensitive information from internal network services.

Cross-protocol redirects from HTTPS to HTTP can bypass the configured agent, and exploitability depends on the deployment environment and reachable internal services.
