CVE-2022-42450
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 · uneditedImproper sanitization of SVG files in HCL Domino Volt allows client-side script injection in deployed applications.
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 confidenceThis is a stored XSS vulnerability in HCL Domino Volt where SVG file uploads are not properly sanitized before rendering. SVG files can contain embedded JavaScript through elements like script tags, event handlers (onload, onclick, etc.), or foreignObject elements. When users view uploaded SVGs in deployed applications, the embedded malicious script executes in their browsers.

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.
-
Confirm HCL Domino Leap installationLocate the HCL Domino Leap installation directory or check installed programs on the server. Look for 'domino leap', 'domino volt', or 'HCL Leap' in program files or the Domino data directory.Affected if The software is present on the system
-
Identify applications with file upload capabilitiesReview Domino Leap applications for forms or fields that accept file attachments. Check application design elements for 'File Upload' or 'Attachment' control types.Affected if Any application accepts file uploads from users
-
Locate uploaded SVG filesSearch the Domino Leap data directory for files with .svg extension. Common paths include the application data folder or attachment storage directories.Affected if SVG files have been uploaded to the system
-
Verify SVG rendering accessibilityDetermine if uploaded SVG files are accessible via web URL. Test by accessing an uploaded SVG directly through the Domino Leap web interface.Affected if Uploaded SVG files are accessible via web browser and can be viewed by other users
-
Check for lack of SVG sanitizationReview application configuration or custom code for SVG sanitization. Examine if any HTML/XML sanitization (DOMPurify, jsanitizer) is applied to uploaded SVG files before storage or display.Affected if No server-side sanitization is performed on SVG uploads before rendering
A user is affected if HCL Domino Leap is deployed with applications that allow SVG file uploads and those SVGs are viewable by users without server-side sanitization.

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 dataImplement server-side sanitization of SVG files using a dedicated HTML/XML sanitization library (such as DOMPurify or jsanitizer) to strip all script content, event handlers, and potentially dangerous SVG elements before storage and rendering. Additionally, configure Content-Security-Policy headers to block inline scripts.
