Threat briefs

A critical vulnerability has been identified in VeloCloud Orchestrator (VCO) On-Prem that allows for remote code execution, enabling a remote attacker to gain privileged access, execute arbitrary commands on the VCO host, and potentially install programs, modify or delete data, or create new user accounts with administrative rights, with impact severity depending on the service account privileges.

Multiple vulnerabilities have been discovered in Samba, a network file sharing service, which could allow a remote attacker to trigger a denial of service, compromise data confidentiality, and bypass security policies.

A vulnerability in the Pocket ID OpenID Connect (OIDC) `createTokenFromRefreshToken` function allows refresh tokens to bypass critical authorization controls, enabling threat actors to maintain perpetual access to client applications even after a user revokes authorization, an administrator disables the user account, or a user is removed from an allowed group.

A missing authentication for critical function vulnerability, tracked as CVE-2026-7187, in Universal Software Inc.'s UKBS product allows attackers to bypass authentication and access functionality not properly constrained by Access Control Lists (ACLs), leading to unauthorized operations.

A flaw in Red Hat OpenShift's oauth-proxy, tracked as CVE-2026-49332, allows an authenticated low-privilege user to smuggle a forged identity header by exploiting differences in how dash and underscore variants of 'X-Forwarded-User' are handled, potentially leading to privilege escalation in upstream applications.

A critical credential exposure vulnerability (CVE-2026-59891) exists in `@sigstore/oci` versions prior to 0.7.1. The `getRegistryCredentials()` function, used to read credentials from `~/.docker/config.json`, employs a substring match instead of an exact host match when selecting credentials. This flaw allows credentials for a legitimate registry (e.g., `ghcr.io`) to be inadvertently transmitted to an attacker-controlled registry if its hostname is a substring of the legitimate one (e.g., `cr.io`). This impacts consumers of `@sigstore/oci` and related GitHub Actions (`actions/attest`, `actions/attest-build-provenance`, `actions/attest-sbom`) when pushing artifacts to untrusted or attacker-influenced destination registries, potentially leading to the leakage of long-lived registry tokens. The vulnerability is fixed in `@sigstore/oci@0.7.1` by enforcing exact host matching.
