Descrição técnica

Psono Server CE && EE versions 0.1.0 through 7.2.3 accepted a user-controlled host when configuring a personal Duo device and passed it to the Duo client without an allowlist or explicit timeout. An authenticated remote attacker could cause the server to connect to selected hosts over HTTPS on port 443 and distinguish failure modes, providing an internal DNS and service-reachability oracle. Connections still required TLS certificate validation, and the flaw did not provide arbitrary protocol or port access. Unresponsive targets could also occupy a server worker until the operating-system timeout.

CVE-2026-1235526.5 MÉD

—

———OpenAM before 16.1.4 contains a server-side request forgery vulnerability in certificate CRL checking that fetches CRLs from the distribution point named in a presented certificate without restricting the destination or verifying the downloaded CRL's signature. Attackers holding a trusted-CA-chained certificate can make OpenAM request internal hosts, capture configured CRL update credentials, overwrite stored revocation data to block certificate authentication for that CA, and tie up authentication threads.12h CVE-2026-1235375.0 MÉD

—

———OpenAM before 16.1.4 contains a server-side request forgery vulnerability that allows parties registering UMA resource sets to trigger internal requests through unvalidated scope description URLs. Attackers can register resource sets with scope URLs pointing to internal hosts or cloud metadata endpoints, which OpenAM fetches when sending pending-request notification emails, enabling internal network probing.12h CVE-2026-1235364.1 MÉD

—

———OpenAM before 16.1.4 contains a server-side request forgery vulnerability that allows administrators, including delegated realm administrators, to make the server fetch arbitrary URLs through federation configuration wizard metadata URLs. Attackers can enter metadata or OpenID Connect discovery URLs pointing to internal hosts or cloud metadata endpoints to probe the internal network and read partial responses.12h CVE-2026-755907.2 ALT

——9IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to access internal network resources and obtain sensitive information due to server-side request forgery. A protection that blocks requests to internal addresses can be bypassed, so the server could be made to contact internal services and return part of their responses.1d CVE-2026-191287.5 ALT
