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 · unedited
Stored Cross-site Scripting (XSS) in Oct8ne Chatbot v2.3. This vulnerability allows an attacker to execute JavaScript code in the victim's browser by injecting a malicious payload through the creation of a transcript that is sent by email. This vulnerability can be exploited to steal sensitive user data, such as session cookies, or to perform actions on behalf of the user, through /Data/SaveInteractions.

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 confidence

Stored Cross-site Scripting (XSS) vulnerability in Oct8ne Chatbot v2.3 allows attackers to inject malicious JavaScript payloads through the /Data/SaveInteractions endpoint when creating chat transcripts. The injected payload persists and executes when the transcript is viewed in the browser or delivered via email, enabling session cookie theft and session hijacking.

MitigationImplement strict input validation and output encoding on the /Data/SaveInteractions endpoint; sanitize all transcript content before rendering in web pages and before embedding in emails; consider implementing Content Security Policy (CSP) headers as defense-in-depth.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Oct8ne Chatbot version
    Locate the installed Oct8ne Chatbot instance and identify its version number through the admin interface, configuration files, or HTTP response headers from the chatbot endpoint. Compare this version to the affected version 2.3.
    Affected if The installed Oct8ne Chatbot version is exactly 2.3.
  2. Verify the /Data/SaveInteractions endpoint exists
    Attempt to access the /Data/SaveInteractions endpoint on the server hosting Oct8ne Chatbot (e.g., https://your-server/Data/SaveInteractions or similar path relative to the chatbot installation). Check if the endpoint responds to HTTP requests.
    Affected if The /Data/SaveInteractions endpoint is accessible and responds to requests.
  3. Check if chat transcript storage is enabled
    Review the Oct8ne Chatbot configuration to determine whether the transcript saving feature is enabled. This may be found in the admin panel under chat settings, or in the configuration file where transcript persistence is defined.
    Affected if Transcript storage is enabled and chat conversations are being saved.
  4. Inspect transcript storage for untrusted input
    Examine the database or file storage where chat transcripts are stored. Look at records created through the /Data/SaveInteractions endpoint to see if user-supplied content (especially messages from chat visitors) is being stored without sanitization.
    Affected if Chat transcripts contain unsanitized user input that could contain malicious scripts.
  5. Verify transcript display in web browser
    Access the chatbot transcript viewing interface (such as the history or logs viewer) in a web browser. View a saved transcript that contains a test script payload to confirm whether the XSS executes when rendered in the browser.
    Affected if Stored JavaScript executes when viewing transcripts in the browser.

A user is affected if they have Oct8ne Chatbot version 2.3 installed with the transcript storage feature enabled and the /Data/SaveInteractions endpoint accessible, resulting in stored XSS executing when transcripts are viewed.

Mitigation

Implement strict input validation and output encoding on the /Data/SaveInteractions endpoint; sanitize all transcript content before rendering in web pages and before embedding in emails; consider implementing Content Security Policy (CSP) headers as defense-in-depth.
