CVE-2025-11952
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 (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 /Records/SendSummaryMail.
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 confidenceStored XSS vulnerability in Oct8ne Chatbot v2.3 allows attackers to inject malicious JavaScript payloads through the transcript creation feature. The vulnerable endpoint /Records/SendSummaryMail does not properly sanitize user input before embedding it in emails, causing the payload to execute in victims' browsers when viewing the sent transcript.

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 Oct8ne Chatbot installationCheck for Oct8ne Chatbot files in your web directory or list installed packages related to oct8neAffected if Oct8ne Chatbot software is present in the environment
-
Verify installed versionLocate version file, changelog, or check application metadata for the exact version numberAffected if Installed version is exactly 2.3
-
Check if /Records/SendSummaryMail endpoint existsAccess the application web interface and navigate to or attempt to access the /Records/SendSummaryMail endpointAffected if The endpoint is accessible and responds to requests
-
Identify transcript creation featureLook for transcript or email summary functionality in the Chatbot admin panel or user interface where users can generate and send conversation transcriptsAffected if Transcript creation/sending feature is enabled and accessible
-
Test for XSS in transcript inputSubmit a test payload containing script tags in any user-controllable field within the transcript feature and check if it gets reflected in the resulting email or page without encodingAffected if User input appears unescaped in the transcript output
A user is affected if Oct8ne Chatbot v2.3 is installed and the /Records/SendSummaryMail transcript feature is accessible and reflects unsanitized input.

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 robust input validation and output encoding on the /Records/SendSummaryMail endpoint to sanitize all user-supplied content before embedding in email transcripts. Consider implementing Content Security Policy (CSP) headers as defense-in-depth.
