Security readout for executives and security teams
Plain-English summary
Authenticated users may be able to view Liferay form entries they should not access by referencing another form record identifier. The known impact is confidentiality loss, not data modification or service outage.
Executive priority
Treat as a moderate-priority privacy and data exposure issue. Prioritize systems collecting regulated, customer, employee, or confidential form data.
Technical view
CVE-2022-42129 is an IDOR in Liferay Dynamic Data Mapping. A remote authenticated user can access form entries through the formInstanceRecordId parameter. Affected ranges include Liferay Portal 7.3.2 through 7.4.3.4, Liferay DXP 7.3 before update 4, and 7.4 GA.
Likely exposure
Exposure is most relevant where Liferay Portal or DXP hosts forms containing sensitive submissions and low-privilege authenticated users have application access.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires authentication and appears limited to unauthorized reading of form entries.
Researcher notes
The CVE maps to CWE-639 and CVSS 3.1 score 4.3. The bundle identifies the vulnerable parameter and affected product ranges, but does not provide detailed patch notes or exploit telemetry.
Mitigation direction
- Identify Liferay Portal and DXP instances using Dynamic Data Mapping forms.
- Check Liferay's advisory and LPE-17448 for vendor-supported fix guidance.
- Upgrade affected deployments to versions outside the listed vulnerable ranges.
- Limit access to sensitive forms to trusted authenticated users until remediated.
- Review form submissions for sensitive data that may need follow-up handling.
Validation and detection
- Inventory deployed Liferay versions and compare them with the affected ranges.
- Confirm whether Dynamic Data Mapping forms are enabled and in use.
- Verify low-privilege users cannot view form entries they do not own.
- Review application logs for unusual access to form entry records.

Authorization Bypass Through User-Controlled Key
Authorization Bypass Through User-Controlled Key represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
