Security readout for executives and security teams
Plain-English summary
This is a medium-severity cross-site scripting issue in Liferay’s Frontend Editor integration with CKEditor. An attacker could cause script or HTML to be injected through specific request parameters, but user interaction is required. The main business risk is session or content manipulation for users who interact with affected pages.
Executive priority
Prioritize remediation in the normal patch cycle, sooner for internet-facing Liferay sites or systems used by privileged editors. This is not marked as actively exploited in the provided sources, but it can affect user trust and administrative sessions.
Technical view
CVE-2022-42116 is CWE-79 XSS affecting Liferay Portal 7.3.2 through 7.4.3.14, Liferay DXP 7.3 before update 6, and DXP 7.4 before update 15. The vulnerable inputs are the name and namespace parameters in the Frontend Editor module’s CKEditor integration. CVSS v3.1 is 6.1, network exploitable, low complexity, no privileges required, user interaction required.
Likely exposure
Exposure is most likely on Liferay Portal or DXP deployments running the listed versions with Frontend Editor and CKEditor integration reachable. Public-facing sites increase concern, especially where authenticated editors or administrators may interact with attacker-influenced content or links.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates remote network reachability, no attacker privileges, and required user interaction. Treat exploitation as plausible but not confirmed by the provided sources.
Researcher notes
Affected product data in the bundle is incomplete in the structured affected field, but the description names Liferay Portal and DXP version ranges. Do not broaden scope beyond those ranges without vendor confirmation. No exploit details or active exploitation evidence are provided.
Mitigation direction
- Identify all Liferay Portal and DXP versions in use.
- Apply Liferay’s fixed update guidance from the vendor advisory.
- Upgrade DXP 7.3 to update 6 or later.
- Upgrade DXP 7.4 to update 15 or later.
- For Portal, check Liferay guidance for releases newer than 7.4.3.14.
- Limit access to affected editor functionality until patched.
Validation and detection
- Confirm whether deployed versions match the affected Liferay Portal or DXP ranges.
- Verify Frontend Editor and CKEditor integration are present or enabled.
- Confirm DXP update level is at or beyond the fixed update threshold.
- Review application logs for suspicious name or namespace parameter activity.
- Perform controlled, non-destructive XSS validation in a test environment only.

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.
