CVE-2022-29853
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 · uneditedOX App Suite through 8.2 allows XSS via a certain complex hierarchy that forces use of Show Entire Message for a huge HTML e-mail message.
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 confidenceOX App Suite through version 8.2 contains a stored XSS vulnerability in its email rendering functionality. Attackers can craft HTML emails with complex hierarchical structures that bypass sanitization checks, particularly when the 'Show Entire Message' feature is triggered for large messages. The malformed HTML allows injection of malicious scripts that execute in the context of the victim's session.

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 OX App Suite versionAccess the admin interface or use system commands to retrieve the installed OX App Suite version number. Common methods include checking the package manager, admin panel 'About' section, or version API endpoint.Affected if Installed version is 7.10.5, 7.10.6, 8.2, or any version lower than 7.10.5
-
Confirm email module is activeVerify that the email rendering functionality is enabled for users. Check admin console settings or user permissions for email access.Affected if Email module is enabled and users can receive/view HTML emails
-
Verify 'Show Entire Message' feature accessibilityCheck whether users have access to the 'Show Entire Message' option, typically available when handling large messages. This may be visible in email client settings or triggered automatically for messages exceeding size thresholds.Affected if Users can trigger 'Show Entire Message' for large email attachments or oversized messages
-
Inspect email sanitization configurationExamine the server configuration files or admin settings for HTML email sanitization. Look for any custom sanitization logic or settings that may override default protection mechanisms.Affected if Sanitization is disabled, customized, or uses a non-robust library that may not handle complex hierarchical HTML structures
Your environment is affected if you run OX App Suite version 7.10.5, 7.10.6, 8.2, or any version below 7.10.5, with the email module enabled and users able to view HTML emails, particularly when the 'Show Entire Message' feature can be triggered.

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 data7.10.5
Implement robust HTML sanitization using a well-established library (e.g., DOMPurify, sanitize-html) with strict allowlists before rendering email content. Consider disabling JavaScript execution in email rendering entirely.
