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
A vulnerability was found in 3scale before version 2.6, did not set the HTTPOnly attribute on the user session cookie. An attacker could use this to conduct cross site scripting attacks and gain access to unauthorized information.

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

3scale before version 2.6 failed to set the HTTPOnly attribute on user session cookies. This allows malicious JavaScript executed via cross-site scripting (XSS) to access and exfiltrate session cookies, potentially enabling attackers to hijack user sessions and gain unauthorized access to the application.

MitigationUpgrade to 3scale version 2.6 or later, which properly sets the HTTPOnly attribute on session cookies to prevent JavaScript-based cookie theft.

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 the installed 3scale version
    Use the system package manager or 3scale administration interface to determine the current version of Red Hat 3scale installed in your environment
    Affected if The version is below 2.6 (e.g., 2.5.x, 2.4.x, earlier)
  2. Verify the session cookie configuration
    Log into the 3scale admin portal or capture an HTTP response from a 3scale-hosted page during user authentication. Inspect the Set-Cookie headers for session cookies
    Affected if The session cookies (such as session identifiers or auth tokens) are missing the HTTPOnly flag in the Set-Cookie header
  3. Confirm the affected cookie names
    Identify which cookies are being set during login/authentication to 3scale applications
    Affected if User session or authentication cookies do not include the HTTPOnly attribute, allowing JavaScript access via XSS

You are affected if your 3scale version is below 2.6 AND session cookies lack the HTTPOnly flag, enabling cookie theft via XSS.
