CVE-2021-41995
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 · uneditedA misconfiguration of RSA in PingID Mac Login prior to 1.1 is vulnerable to pre-computed dictionary attacks, leading to an offline MFA bypass.
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 confidencePingID Mac Login prior to version 1.1 contains a misconfigured RSA implementation that uses weak or static cryptographic parameters vulnerable to pre-computed dictionary attacks, allowing attackers to bypass MFA verification offline without requiring the second factor.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 PingID Mac Login is installedCheck for PingID application in /Applications folder, or run: ls /Applications | grep -i pingidAffected if PingID Mac Login application exists on the system
-
Determine installed versionRight-click PingID.app > Get Info, or run: defaults read /Applications/PingID.app/Contents/Info CFBundleShortVersionStringAffected if Version returned is below 1.1 (e.g., 1.0.x or earlier)
-
Confirm PingID is configured for Mac loginCheck system login settings: inspect /Library/Application Support/PingID/ configuration directory, or check if PingID is listed as an authorized login method in system preferencesAffected if PingID is set as the MFA mechanism for local authentication and version is below 1.1
User is affected if PingID Mac Login version is installed and is below 1.1, and PingID is configured as the login authentication method.

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.
dbcve · scoped1.1
Upgrade PingID Mac Login to version 1.1 or later to obtain the corrected RSA implementation; no configuration-based workaround is available.
1.1
- Upgrade PingID Integration For Mac Login to version 1.1 or later
- After upgrading, verify the version number matches the expected fixed release
- Test the MFA authentication flow to confirm the vulnerability is remediated
