CVE-2023-49119
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 · uneditedStored cross-site scripting vulnerability via the img tags exists in GROWI versions prior to v6.0.0. If this vulnerability is exploited, an arbitrary script may be executed on the web browser of the user who accessed the site using the product.
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 · high confidenceGROWI versions prior to v6.0.0 contain a stored cross-site scripting (XSS) vulnerability in img tag handling. Attackers can inject malicious scripts into img tags that persist on the server and execute in the browsers of users who view the affected content.

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 GROWI versionRun `npm list growi` in the application directory, check the package.json file, or look at the GROWI admin dashboard under System Information > VersionAffected if The installed version is prior to v6.0.0 (e.g., v5.x.x, v4.x.x)
-
Determine if user-generated content is enabledCheck the GROWI configuration for markdown/HTML rendering settings, typically found in /admin/app-settings or the config.yaml fileAffected if Users can create or edit pages with markdown or HTML content containing img tags
-
Inspect stored content for img tag injectionsQuery the database (MongoDB) for page content containing img tags, for example: `db.pages.find({ revision: { $regex: '<img' } })` or use the GROWI admin page searchAffected if Any pages contain img tags with suspicious attributes such as onerror, onload, or javascript: URLs
-
Check server logs for XSS exploitation attemptsReview web server and GROWI access logs for patterns like `<img` combined with event handlers or unusual URL schemesAffected if Logs contain requests with img tags containing javascript:, onerror, or similar XSS vectors
You are affected if GROWI is installed at a version lower than v6.0.0 AND the platform allows users to create or view content with img tags.
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 · scoped6.0.0
Upgrade GROWI to v6.0.0 or later. Review existing content for any malicious img tag injections that may have been stored prior to patching.
6.0.0
- Review the current Growi installation and note the current version
- Backup the existing Growi database and configuration files
- Consult the official GROWI upgrade documentation for upgrading to version 6.0.0
- Stop the running GROWI service
- Upgrade GROWI to version 6.0.0 using the appropriate method (package manager, Docker, or manual update)
- Verify the upgrade was successful by checking the version number
- Restart the GROWI service
- Test that the application functions correctly and the XSS vulnerability is mitigated
