Summary
A vulnerability in the ironic-image container image allows access to the Ironic API without authentication if it is not deployed with TLS and does not have API and Conductor split into separate services. If there is no firewall, the API could be accessed by anyone on the network.
Risk Assessment
The organization is at risk of unauthorized access to the Ironic API, which could lead to serious security breaches and data loss. Inadequate security configuration may result in unauthorized resource exploitation.
Recommendation
It is recommended to implement TLS for the Ironic API and configure proper authentication. Alternatively, the Ironic API and Conductor can be split, but this method is not recommended.

This vulnerability enables unauthenticated remote code execution (RCE) on a victim's machine by exploiting a combination of cryptographic weaknesses and memory management issues in the SConnect native host component. The attack leverages an unrestricted messaging interface between an attacker-controlled web page and the native host, allowing malicious input to bypass security checks.

In GetSimple CMS CE prior to version 1.5, the UpdateCE update form lacked an anti-CSRF token and the POST handler did not verify token or request origin. A remote attacker can host a page that auto-submits a forged POST; when an authenticated admin visits it, the server performs an attacker-directed download-and-deploy operation, leading to remote code execution. The url field is also written unescaped, allowing HTML injection.
- CVE-2026-56660Critical
In GetSimple CMS CE prior to version 1.5, the update handler in UpdateCE.php downloads a ZIP archive and extracts it into the web root without validating file types or extraction paths. Because PHP files are written into a web-accessible directory, an attacker who can cause a malicious archive to be processed achieves remote code execution as the web-server user. Entry names are also used unsafely, allowing directory traversal (../) to write files outside the intended directory.
- CVE-2026-14984Critical
Teledyne FLIR Aware2 versions through 6.9.0.2 transmit data in cleartext in primary control endpoints. Remote unauthenticated attackers can intercept, hijack, or modify session traffic against PackBot robots via sniffing or hijacking network traffic.

Original NVD description (English source)
ironic-image is a container image to run OpenStack Ironic as part of Metal³. Prior to version capm3-v1.4.3, if Ironic is not deployed with TLS and it does not have API and Conductor split into separate services, access to the API is not protected by any authentication. Ironic API is also listening in host network. In case the node is not behind a firewall, the API could be accessed by anyone via network without authentication. By default, Ironic API in Metal3 is protected by TLS and basic authentication, so this vulnerability requires operator to configure API without TLS for it to be vulnerable. TLS and authentication however should not be coupled as they are in versions prior to capm3-v1.4.3. A patch exists in versions capm3-v1.4.3 and newer. Some workarounds are available. Either configure TLS for Ironic API (`deploy.sh -t ...`, `IRONIC_TLS_SETUP=true`) or split Ironic API and Conductor via configuration change (old implementation, not recommended). With both workarounds, services are configured with httpd front-end, which has proper authentication configuration in place.
