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 cookie management issue was addressed with improved state management. This issue is fixed in Security Update 2022-003 Catalina, macOS Big Sur 11.6.5. Processing maliciously crafted web content may disclose sensitive user information.

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

A cookie management vulnerability in WebKit allows maliciously crafted web content to potentially disclose sensitive user information due to improper state management of cookies. The vulnerability enables a web-based attacker to access sensitive data through mishandled cookie states.

MitigationApply Apple Security Update 2022-003 for macOS Catalina or update to macOS Big Sur 11.6.5 or later to patch the WebKit vulnerability.

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. Identify the operating system
    Run 'uname -a' or check /etc/os-release for Fedora, or 'sw_vers' for macOS
    Affected if System is Fedora 35 or 36, or macOS 10.15.x (before 10.15.7), or macOS 11.0-11.6.4
  2. Check Fedora WebKit version
    Run 'rpm -qa | grep webkit2gtk' to list installed WebKit packages, then 'rpm -q --changelog webkit2gtk' or check the package version against Fedora security advisories
    Affected if WebKit version is present on Fedora 35 or 36 and has not been patched via Fedora update
  3. Check macOS version
    Click Apple menu > About This Mac to view the exact macOS version number
    Affected if Version shows 10.15.7 or earlier, or shows 11.0 through 11.6.4
  4. Verify WebKit-based browser usage
    Check for installed WebKit browsers such as Epiphany (Fedora), Safari (macOS), or any third-party browser using WebKit engine
    Affected if WebKit-based browser is in regular use on an affected system version
  5. Confirm cookie storage access
    Inspect cookie storage location: on macOS check ~/Library/Cookies or on Fedora check ~/.cache/webkitgtk or browser-specific cookie databases
    Affected if User has active cookies stored from web browsing sessions

A user is affected if they run Fedora 35/36 or macOS 10.15 through 11.6.4 with any WebKit-based browser and browse the web, since the vulnerability triggers through malicious web content accessing cookie state.
