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
When a TLS Certificate error occurs on a domain protected by the HSTS header, the browser should not allow the user to bypass the certificate error. On Firefox for Android, the user was presented with the option to bypass the error; this could only have been done by the user explicitly. <br>*This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102.

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

On Firefox for Android versions prior to 102, users could bypass TLS certificate errors on HSTS-protected domains, circumventing HSTS security protections against man-in-the-middle attacks. The browser incorrectly presented an option to proceed despite the certificate error on domains protected by the HSTS header, requiring explicit user action to bypass.

MitigationUpgrade Firefox for Android to version 102 or later to receive the security fix.

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 Firefox for Android is installed
    Open Android Settings, go to Apps, and look for Firefox in the app list. Alternatively, use ADB command: adb shell pm list packages | grep -i firefox
    Affected if Firefox for Android is not found on the device, so the vulnerability does not apply
  2. Identify the Firefox for Android version
    In Android Settings, go to Apps > Firefox > App info to view the version number. Alternatively, use ADB: adb shell dumpsys package org.mozilla.firefox | grep versionName
    Affected if The version displayed is below 102.0 (for example, 101.x, 100.x, etc.)
  3. Verify the vulnerable configuration is present
    This vulnerability is present by default in affected versions - no special configuration need be checked. The flaw is in how the browser handles certificate errors on HSTS-protected domains.
    Affected if The installed version is any version of Firefox for Android prior to 102.0

If Firefox for Android version 102.0 or higher is installed, the environment is not affected; otherwise, if the version is below 102.0, the user is affected by this vulnerability.
