CVE-2025-52639
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHCL Connections is vulnerable to a sensitive information disclosure vulnerability which could allow a user to obtain sensitive information they are not entitled to, caused by improper rendering of application data.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHCL Connections contains a sensitive information disclosure vulnerability where improper rendering of application data allows authenticated users to access sensitive information they are not entitled to view. The vulnerability stems from insufficient access control checks during the data rendering process, potentially exposing confidential content to unauthorized users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed HCL Connections versionCheck the installed version of HCL Connections in your environment. This is typically visible in the product administration console, About page, or version documentation. Common locations include the IBM/WebSphere console or the Connections admin interface.Affected if The installed version is exactly 8.0 (HCL Connections 8.0)
-
Verify data rendering features are activeConfirm that the HCL Connections application is actively serving content to users. The vulnerability affects data rendering processes, so determine if the core application services are running and serving content to authenticated users.Affected if The application services are running and users can access Connections content
-
Review access control configurationsExamine the access control lists (ACLs) and permission settings within HCL Connections. Check whether proper boundaries exist between different user roles and communities. Look for any overly permissive settings that could allow cross-role data access.Affected if Access control settings allow authenticated users to access data outside their intended permissions, or if role-based restrictions are not properly enforced
-
Check for sensitive data exposure indicatorsReview application logs and audit trails for any instances where users accessed content outside their assigned communities, files, or data domains. Look for access events that deviate from expected user-community associations.Affected if Audit logs or user access patterns show authenticated users accessing content they were not explicitly entitled to view
Your environment is affected if you are running HCL Connections version 8.0 and the application is actively serving data to authenticated users without proper access control enforcement on rendered content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-supplied patch for CVE-2025-52639 which addresses proper data rendering and access control enforcement. Review user permissions and data access controls as part of remediation verification.
