Summary
In the OSAC operator (revision 8220502), the console-proxy RemoteConfigResolver parses Kubernetes Secret kubeconfig data without sanitizing the resulting rest.Config. An attacker able to create or modify a Secret with the osac.openshift.io/remote-cluster-kubeconfig label can supply an exec credential plugin, causing arbitrary process execution as the console-proxy service account, while an attacker-controlled server address enables SSRF from the proxy pod.
Risk Assessment
An attacker with write access to Secrets in the namespace can achieve code execution in the proxy pod and make requests to internal resources (SSRF). Remote and auto cluster modes are affected; local mode is not.
Recommendation
Apply the fix from commit 7e4222b for the credential-plugin execution path and restrict permissions to create or modify Secrets labeled osac.openshift.io/remote-cluster-kubeconfig. Note that the patch does not address the server-address SSRF path, so add network restrictions as well.

The BuddyPress XProfile Image Field plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 3.1.0.

The s2Member plugin for WordPress in versions up to and including 260927 is vulnerable to Remote Code Execution via the 'item_name' parameter. Insufficient sanitization in strip_php_tags_deep() only strips literal '<?' sequences, and a post-interpolation placeholder cleanup reassembles a valid '<?php' opener after the attacker-controlled value has already been embedded in the email template.
- CVE-2026-97718Critical
CVE-2026-97718 is a cross-site request forgery vulnerability in version 14.60 of the Secure Access server. Because of a bypassed security control, an attacker can cause an admin to create an account under their control.
- CVE-2026-116769Critical
CVE-2026-116769 is an authentication bypass vulnerability in Secure Access servers starting with version 13.0 and prior to 14.61. Attackers can modify security settings of a client via the server.
- CVE-2026-102435Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

Original NVD description (English source)
OSAC operator is a Kubernetes operator. In the affected revision identified as 8220502, the `console-proxy` `RemoteConfigResolver` parses Kubernetes Secret kubeconfig data with `clientcmd.RESTConfigFromKubeConfig` without sanitizing the resulting `rest.Config`. An attacker who can create or modify a Secret labeled `osac.openshift.io/remote-cluster-kubeconfig`: "true" in a namespace where the proxy's RoleBinding grants Secret read access can supply `users[].user.exec`. When `rest.TransportFor` builds the HTTP transport for an upstream WebSocket connection, client-go invokes that exec credential plugin, spawning an arbitrary process as the osac-`console-proxy` service account inside the pod. Attacker-controlled `clusters[].server` also enables server-side request forgery from the proxy pod. Remote and auto VM cluster modes are affected, with auto the default; exclusively `local` mode does not read kubeconfig Secrets and is unaffected. The credential-plugin execution path is patched in commit 7e4222b; that patch does not address the described server-address SSRF path.
