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

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

Yandex Browser for desktop before version 17.1.1.227 fails to display Protect (safebrowsing) warnings when visiting websites with certain 'special content-type' HTTP headers. This allows remote attackers hosting malicious websites to bypass the browser's security warnings and present harmful content without triggering the Protect warning system.

MitigationUpdate Yandex Browser to version 17.1.1.227 or later. For enterprise environments, deploy the browser update via standard patch management and verify the Protect feature functions correctly after installation.

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 Yandex Browser is installed
    Locate the Yandex Browser executable (typically in Program Files or Program Files (x86) folder under Yandex\YandexBrowser) or check the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Yandex\YandexBrowser or HKEY_CURRENT_USER\SOFTWARE\Yandex\YandexBrowser
    Affected if Yandex Browser executable or registry key is found on the system
  2. Identify installed Yandex Browser version
    Right-click the browser executable (typically named browser.exe), select Properties, and check the Details tab for the Product Version field. Alternatively, launch the browser and navigate to chrome://version to view version information.
    Affected if The displayed version number is lower than 17.1.1.227 (for example, 17.1.0.XXX or any earlier release)
  3. Verify Protect (safebrowsing) feature is enabled
    Navigate to the browser Settings, then go to Security settings and confirm that the Protect feature is turned on. This can also be checked via chrome://settings/security in the address bar.
    Affected if Protect is enabled and the browser version is below 17.1.1.227

The environment is affected if Yandex Browser version is below 17.1.1.227 and the Protect safebrowsing feature is enabled, as the vulnerability allows malicious websites to bypass security warnings.
