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
Whale browser before 3.12.129.18 allowed extensions to replace JavaScript files of the HWP viewer website which could access to local HWP files. When the HWP files were opened, the replaced script could read the files.

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

Whale browser before version 3.12.129.18 contained a vulnerability in its extension system where malicious extensions could replace JavaScript files of the built-in HWP (Hangul Word Processor) viewer website. When users opened local HWP files using the browser's viewer, the replaced script could execute and read the file contents, leading to local file disclosure.

MitigationUpdate Whale browser to version 3.12.129.18 or later to obtain the vendor patch. Review installed browser extensions and remove any untrusted or unnecessary extensions as a defense-in-depth measure.

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 Whale browser is installed
    Check for Navercorp Whale browser installation on the system. Look for Whale in installed applications or check common installation paths.
    Affected if Whale browser is installed on the system
  2. Identify installed Whale browser version
    Access Whale browser settings or about page to view the version number. Typically found in Settings > About Whale or by navigating to whale://version in the address bar.
    Affected if The installed version is lower than 3.12.129.18
  3. Verify HWP viewer usage or configuration
    Check if the built-in HWP viewer feature is enabled or has been used. Look for HWP file handling associations or viewer settings within Whale browser.
    Affected if HWP viewer feature is enabled or HWP files have been opened in the browser
  4. Review installed browser extensions
    Access Whale's extension management page (whale://extensions) to list all installed extensions. Note any untrusted or unnecessary extensions that could potentially contain malicious code.
    Affected if Extensions with elevated privileges or untrusted origins are installed that could modify built-in viewer scripts

A user is affected if Whale browser version is below 3.12.129.18 and either the HWP viewer feature is in use or extensions with sufficient privileges are present that could exploit the JavaScript replacement vulnerability.
