phpSysInfo has an IP allowlist (PSI_ALLOWED) bypass via spoofed X-Forwarded-For / Client-IP headers

Summary phpSysInfo's PSIALLOWED IP allowlist can be trivially bypassed by any unauthenticated remote attacker. The access-control check in readconfig.php derives the client IP from the attacker-controlled X-Forwarded-For and Client-IP HTTP headers before falling back to REMOTEADDR. An attacker ca...

CVE-2026-76835

OAuth2 Proxy honours a client-supplied X-Forwarded-Uri header when deciding whether a request may skip authentication, because the guard added for CVE-2026-40575 is inert in the default reverse-proxy configuration.
