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 flaw was found In 3Scale Admin Portal. If a user logs out from the personal tokens page and then presses the back button in the browser, the tokens page is rendered from the browser cache.

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

The 3Scale Admin Portal fails to properly clear browser cache upon logout from the personal tokens page. When a user logs out and presses the browser back button, the cached version of the tokens page remains accessible, exposing sensitive personal API tokens to anyone with access to the browser.

MitigationImplement cache-control headers (no-store, no-cache, must-revalidate) on the tokens page and ensure proper session/cache invalidation on logout to prevent cached sensitive data from being retrieved after authentication termination.

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 3scale version
    Check the installed version of Red Hat 3scale API Management in your environment. This may be visible in the admin console, system diagnostics, or package management system. Compare your installed version against the affected range: version 2.0
    Affected if The installed version is exactly 2.0 (matching the affected product version)
  2. Inspect tokens page cache headers
    Access the personal tokens page in the 3scale Admin Portal. Use browser developer tools or a proxy to capture the HTTP response headers for this page. Examine whether the response includes cache-control headers such as 'no-store', 'no-cache', or 'must-revalidate'
    Affected if The tokens page response lacks proper cache-control headers (no-store, no-cache, must-revalidate) or contains only default caching headers
  3. Test browser back button behavior after logout
    Log into the 3scale Admin Portal, navigate to the personal tokens page to generate or view a token, then log out. Without re-authenticating, press the browser back button and observe whether the cached tokens page loads with sensitive token data visible
    Affected if After logout, the browser back button displays the cached tokens page with visible sensitive information
  4. Verify logout endpoint cache handling
    Capture and analyze the HTTP response headers from the logout endpoint. Check whether the logout action returns cache-control headers that instruct the browser not to cache the sensitive tokens page content
    Affected if The logout response does not include cache-invalidation headers or does not clear the tokens page from browser cache

Your environment is affected if you are running 3scale version 2.0 and the personal tokens page or logout process lacks proper cache-control headers, allowing cached sensitive tokens to remain accessible after logout.

Mitigation

Implement cache-control headers (no-store, no-cache, must-revalidate) on the tokens page and ensure proper session/cache invalidation on logout to prevent cached sensitive data from being retrieved after authentication termination.
