Security readout for executives and security teams
Plain-English summary
CVE-2025-23366 is a cross-site scripting flaw in the WildFly HAL management console. A privileged, authenticated attacker could place unsafe input into a page viewed by other users, potentially exposing sensitive information or enabling unauthorized actions in their browser session. The required management role limits exposure, but compromise of an administrator-level account increases the business risk.
Executive priority
Prioritize remediation during the next security maintenance window, accelerating it where EAP 8 management consoles are externally reachable or privileged access is weakly controlled. This is not supported as an emergency active-exploitation event, but administrator-facing confidentiality and integrity consequences justify prompt action.
Technical view
The HAL Console incorrectly neutralizes user-controlled input before including it in web output, classified as CWE-79. Exploitation requires authentication and membership in the SuperUser, Admin, or Maintainer management groups. The supplied CVSS 3.1 score is 6.5, with high confidentiality and integrity impact, no availability impact, low complexity, and high privileges required.
Likely exposure
The bundle identifies org.jboss.hal/hal-console in Red Hat JBoss Enterprise Application Platform 8 as affected. EAP 7 and the Expansion Pack are marked unaffected; JBoss Data Grid 7 status is unknown. Exact affected and fixed version ranges are not supplied. Internet-accessible or broadly reachable management consoles and excessive privileged membership increase exposure.
Exploitation context
The source bundle does not identify active exploitation, and the CVE is not listed as KEV. Exploitation nevertheless requires network access to the management console and an authenticated account in a powerful management group. No evidence in the bundle establishes public exploit availability or observed attacks.
Researcher notes
The primary exposure is stored or otherwise rendered XSS within a privileged management context. The stated vector is AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N. Product status is clearest for EAP 8, while precise vulnerable and corrected versions are absent from the bundle. Validate package-level applicability through the linked Red Hat advisories.
Mitigation direction
- Review the applicable Red Hat errata and install the vendor-provided security update for each affected deployment.
- Restrict HAL management-console access to trusted administrative networks and authorized operators.
- Review SuperUser, Admin, and Maintainer membership; remove unnecessary or stale privileged accounts.
- Monitor privileged management activity and investigate unexpected console changes or administrator sessions.
Validation and detection
- Inventory EAP 8 deployments and record their installed HAL Console package versions.
- Compare installed packages against the applicable Red Hat errata; the bundle does not provide fixed version ranges.
- Confirm EAP 7 and Expansion Pack assets match the products marked unaffected in the source bundle.
- Treat JBoss Data Grid 7 status as unresolved and verify it directly through current vendor guidance.
- Audit management-group membership and confirm the console is not exposed beyond intended administrative networks.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
