CVE-2023-37496
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 Verse is susceptible to a Stored Cross Site Scripting (XSS) vulnerability. An attacker could execute script in a victim's web browser to perform operations as the victim and/or steal the victim's cookies, session tokens, or other sensitive information.
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 Verse contains a stored Cross Site Scripting (XSS) vulnerability allowing attackers to inject malicious scripts that persist in the application and execute in victims' browsers when viewed, potentially enabling session hijacking and unauthorized actions.

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.
-
Check HCL Verse versionAccess the HCL Verse admin console or check the installed package version. The version is typically displayed in the About section or can be retrieved via the command line interface if available.Affected if The installed version is lower than 3.1
-
Identify user input fieldsReview HCL Verse for features that accept user-submitted content such as email compose, calendar entries, contact information, or document annotations.Affected if User-submitted content can be stored and viewed by other users
-
Verify output encoding statusInspect the applications response headers and HTML output to determine if user-provided content is being properly encoded before rendering in the browser.Affected if User content is rendered without proper encoding or sanitization
-
Review stored content for suspicious scriptsQuery the HCL Verse database or examine stored user content for any HTML script tags, JavaScript event handlers, or other malicious script injections.Affected if Malicious scripts are found stored in the application database
If HCL Verse version is below 3.1 and the application stores and displays user-submitted content without proper sanitization, the environment is vulnerable to CVE-2023-37496
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped3.1
Apply available vendor security patches for HCL Verse; until patch is available, implement output encoding and input validation on user-submitted content.
3.1
- Access the HCL Verse download portal or contact HCL support to obtain version 3.1 or later
- Follow the standard HCL Verse upgrade documentation for your deployment type (on-premises or SaaS)
- For on-premises deployments: back up your existing Verse data and configuration
- Install version 3.1 or later following HCL's installation instructions
- Verify the upgrade was successful and test that the application functions normally
- Confirm the XSS vulnerability is resolved by validating that user input is properly sanitized in the Verse application
