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 confidenceOn Android, Firefox's password manager failed to properly enforce device PIN authentication before allowing users to view saved passwords, bypassing a security control intended to protect sensitive credential data. This affects Firefox versions prior to 133 on Android devices.
