Descrição técnica

Google::Auth versions 0.12 for Perl allow server side request forgery via unvalidated credential_source URLs in AWS external account credentials. An external_account configuration with the AWS subject token type selects Google::Auth::ExternalAccountCredentials::Aws. Its retrieve_subject_token sends requests to the imdsv2_session_token_url, url and region_url fields of credential_source without the host check that the other credential classes apply. Any caller that builds credentials from a configuration it does not fully control issues GET and PUT requests to hosts the configuration names, including internal services and link-local metadata endpoints.

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.6h 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.6h 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.6h 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
