# CVE-2026-2586: GlassFish's Administration Console is Vulnerable to RCE

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8% , percentile 57: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 57% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes org.glassfish.main.admingui:console-common (Maven) < 8.0.2, fixed in 8.0.2 ; org.glassfish.jsftemplating:jsftemplating (Maven) < 4.2.0, fixed in 4.2.0 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- Maven `org.glassfish.main.admingui:console-common` < 8.0.2 → fixed: 8.0.2
- Maven `org.glassfish.jsftemplating:jsftemplating` < 4.2.0 → fixed: 4.2.0

## Affected products (CVE record)

- Eclipse Foundation Eclipse Glassfish: 7.0.0 < 7.0.26, 7.1.0 < 7.1.1, 8.0.0 < 8.0.2

## Severity

- eclipse CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.83% probability of exploitation activity in the next 30 days; percentile 57.
