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
Cross-Site Request Forgery (CSRF) vulnerability in REVE Chat REVE Chat revechat allows Stored XSS.This issue affects REVE Chat: from n/a through <= 6.4.4.

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 confidence

A CSRF vulnerability in REVE Chat version <= 6.4.4 allows attackers to trick authenticated users into triggering requests that inject malicious scripts, resulting in Stored XSS. The attack leverages the lack of CSRF protection to persistently embed malicious code that executes when other users view the compromised content.

MitigationUpgrade to a patched version of REVE Chat and implement CSRF tokens with SameSite cookie attributes, combined with output encoding and input sanitization to prevent XSS injection.

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. Identify REVE Chat version
    Locate the version number in the application footer, About page, or admin dashboard settings. Check any /about, /settings, or help menu entries.
    Affected if Installed version is 6.4.4 or lower
  2. Verify CSRF token implementation
    Inspect the HTML source of any REVE Chat forms (login, chat settings, agent dashboard) and check if hidden input fields containing_csrf_token or similar anti-CSRF tokens are present.
    Affected if Forms lack hidden CSRF token fields
  3. Check SameSite cookie attributes
    Use browser developer tools or curl to inspect cookies set by REVE Chat. Examine the Set-Cookie headers for SameSite=Strict or SameSite=Lax attributes.
    Affected if Cookies lack SameSite attribute or have SameSite=None without Secure flag
  4. Test for XSS payload persistence
    If you have test access, use two different browser sessions. Submit a script tag in a chat message or agent note from one session and verify if it executes when viewed in another session.
    Affected if Stored XSS executes across sessions without sanitization

You are affected if REVE Chat version is 6.4.4 or lower AND forms lack CSRF tokens, allowing stored XSS injection that persists across user sessions.
