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
Idira Identity Browser Extension (Chrome, Firefox, and Edge builds) versions prior to 26.8.1 exhibit an origin validation flaw within its internal web-page verification routines. If an authenticated user navigates to a specially crafted webpage, this interaction could potentially allow a remote attacker to trigger unauthorized application interaction or execution parameters within the context of that authenticated browser session. CyberArk Security Bulletin: CA26-21

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.

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. Check if Idira Identity Browser Extension is installed
    Open your browser's extension management page: Chrome/Edge go to chrome://extensions, Firefox go to about:addons and click Extensions. Look for 'Idira Identity Browser Extension' in the list.
    Affected if The extension is not found in the browser's extension list.
  2. Locate the installed version number
    In the extensions page, enable Developer mode (Chrome/Edge) or look for the version info in the extension details (Firefox). Click on the Idira Identity extension to view its version number, typically displayed as 'Version: X.X.X' next to the extension name.
    Affected if No version number is displayed or the extension is not present.
  3. Compare version against vulnerable range
    Compare the installed version to the affected range: vulnerable if version is 26.0.0 through 26.8.0 (inclusive). For example, versions 26.0.0, 26.4.2, or 26.8.0 are affected. Versions 26.8.1 and later, or versions prior to 26.0.0, are not in the vulnerable range.
    Affected if Installed version is >= 26.0.0 and < 26.8.1.
  4. Check all browsers
    Repeat steps 1-3 for each browser (Chrome, Firefox, Edge) installed on the system where the Idira Identity Browser Extension may have been added.
    Affected if Any browser has the extension installed with a vulnerable version.

The user is affected if the Idira Identity Browser Extension is installed with version 26.0.0 or higher but lower than 26.8.1 in any browser.
