Risk Analysis

This critical authenticated Remote Code Execution (RCE) vulnerability in GlassFish's Administration Console allows users with access to execute arbitrary operating system commands. With a CVSS score of 9.1, this flaw poses a high risk of system compromise if an authenticated attacker gains access.

No public exploit is currently known for this vulnerability. While it requires authentication, its remote exploitability and low attack complexity make it a significant threat once an attacker has credentials.

Recommended Action

Upgrade Eclipse Glassfish to a patched version. Implement strong authentication and access controls for the Administration Console, and ensure only trusted users have access.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2026-2586 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
