CVE-2022-42955
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 · uneditedThe PassWork extension 5.0.9 for Chrome and other browsers allows an attacker to obtain cleartext cached credentials.
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 confidenceThe PassWork password manager browser extension version 5.0.9 stores cached credentials in cleartext rather than encrypting them, allowing an attacker with local access or the ability to execute code in the user's browser context to retrieve plaintext passwords from the extension's cache.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify PassWork browser extension is installedOpen your browser's extension management page (chrome://extensions for Chrome/Edge/Brave, about:addons for Firefox) and look for 'PassWork' in the installed extensions listAffected if PassWork extension is present in the browser
-
Check the installed extension versionOn the extensions management page, locate the PassWork entry and note the version number displayed. In Chrome-based browsers, enable 'Developer mode' to reveal version details. In Firefox, click on the PassWork extension and view the version in the details panelAffected if Version shown is exactly 5.0.9
-
Inspect extension storage for cleartext credentialsUse browser developer tools: open the Application tab, select 'Storage' then 'Indexed DB' or 'Local Storage' under the extension's origin. Look for database entries containing password data. Alternatively, navigate to the extension's user data folder in your browser profile (typically under Extensions/PassWork or similar path) and examine JSON or database files storing credentialsAffected if Password values appear in plaintext (unencrypted) within storage files or IndexedDB entries
User is affected if PassWork browser extension version 5.0.9 is installed and credentials are stored without encryption in the extension's local storage or IndexedDB

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version of PassWork when available; as a temporary measure, avoid using the extension on shared or compromised systems until the vulnerability is remediated.
