About Hpe Autopass License Server
CVE-2026-23600 affects Hpe Autopass License Server, a product from Hpe. Before acting, confirm where Hpe Autopass License Server runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: A remote authentication bypass vulnerability exists in HPE AutoPass License Server (APLS).
The weakness class is Improper Authentication. The software does not properly prove who a user is.
Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Hpe Autopass License Server and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Hpe Autopass License Server named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

Frequently asked questions
Related CVEs
A vulnerability in the web-based management interface of AOS-CX switches exposes some sessions to a lack of Cross-Site Request Forgery (CSRF) protection. This could allow a remote unauthenticated attacker to execute arbitrary input against the affected interface if the attacker can convince an authenticated user of the interface to interact with a specially crafted URL.
A vulnerability exists in the Credential Manager component that may allow for unauthorized administrative access. An unauthenticated remote attacker could exploit this vulnerability on a device in its factory-default or post-ZTP state before any administrator has configured credentials by providing a predictable factory-default password. Successful exploitation could result in full administrative control of the affected device during the initial setup process.
A vulnerability exists in a management component that could allow an unauthenticated adjacent attacker to execute arbitrary commands. Successful exploitation could result in remote execution of arbitrary commands in the context of the affected utility.
An authenticated user with low-privileged access could submit crafted input through the web-based management interface to execute arbitrary commands on the underlying operating system.
Vulnerabilities exist in the authentication module that may improperly process malformed or truncated input. An authenticated remote attacker could exploit these vulnerabilities by providing specially crafted input from a compromised or hostile authentication server. Successful exploitation could result in a Denial-of-Service or potential remote code execution with elevated privileges.
Multiple vulnerabilities exist in a daemon of AOS-CX that may allow for improper processing of malformed input. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted packets to the affected service. Successful exploitation could result in remote code execution with elevated privileges.
