CVE-2026-2586: An authenticated Remote Code Execution (RCE) vulnerability was identified in GlassFish's Administration Console.

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.84% (FIRST EPSS); higher than 57.7% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Eclipse Foundation Eclipse Glassfish 7.0.26, 7.1.1, 8.0.2.

Low priority for now. Upgrade to Eclipse Foundation Eclipse Glassfish 7.0.26, 7.1.1, 8.0.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An authenticated Remote Code Execution (RCE) vulnerability was identified in GlassFish's Administration Console. A user with access to the panel can send crafted requests that allow the execution of arbitrary operating system commands with the privileges of the application service user. This issue affects Eclipse GlassFish: from 8.0.0 to 8.0.1, fixed in 8.0.2; 7.1.0, fixed in 7.1.1; from 7.0.0 to 7.0.25, fixed in 7.0.26. Impact on versions from 5.1.0 to 6.2.5 is unknown.
