CVE-2023-30968
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 · uneditedOne of Gotham Gaia services was found to be vulnerable to a stored cross-site scripting (XSS) vulnerability that could have allowed an attacker to bypass CSP and get a persistent cross site scripting payload on the stack.
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 confidenceA stored cross-site scripting (XSS) vulnerability in a Gotham Gaia service allows attackers to inject malicious scripts that persist on the stack. The vulnerability is particularly severe because it bypasses Content Security Policy (CSP), a security control designed to prevent XSS attacks by restricting script sources.

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 Gotham Gaia service installationSearch for Gotham Gaia service processes, services, or containers in your environment. Check for any web applications or APIs named Gotham Gaia or associated with this service.Affected if The Gotham Gaia service is present and running in the environment
-
Determine Gotham Gaia versionCheck the installed version of Gotham Gaia by reviewing application metadata, service information, or version files if available. Compare this version to any affected ranges if documented.Affected if A version of Gotham Gaia is running and matches affected version ranges (if known)
-
Inspect Content Security Policy headersCapture HTTP responses from the Gotham Gaia web interface or API endpoints. Examine CSP headers (Content-Security-Policy) to verify if CSP is implemented.Affected if CSP headers are present but can be bypassed, or are missing entirely
-
Review input handling for stored dataIdentify features where user input is stored and later displayed to users (database entries, user profiles, comments, logs). Check if input validation and output encoding are applied before storage and display.Affected if User-supplied data can be stored and retrieved without proper sanitization or encoding
Your environment is affected if the Gotham Gaia service is running and user input can be persisted and displayed back to users without proper input validation and output encoding, particularly if CSP can be bypassed.

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 dataFix the stored XSS vulnerability through proper input validation and output encoding, then review and strengthen the CSP policy to prevent bypass attempts.
