Auditing a browser extension for credential storage vulnerabilities involves tracing the full credential lifecycle from input to on-disk storage, checking cryptographic implementation, logging practices, and git history for both unreleased and production branches to produce severity-ranked findings with remediation steps.

Assessing git history for unreleased security flaws requires reviewing both the latest tagged production release and the unreleased main branch code, checking for leaked credentials, bad logging practices, and cryptographic weaknesses to ensure no critical risks reach end users.

You can distinguish actual security risks from acceptable implementation patterns during a vulnerability assessment by using a false-positive guardrail table, which aligns findings with the repository's official security rules to reduce wasted review time on acceptable code structures.

Classifying severity levels for crypto audit findings involves ranking vulnerabilities as Critical, High, Medium, or Low based on their potential to expose stored credentials, providing clear remediation steps aligned with the extension's biometric and security rules.

This security audit approach covers shared public computer attack surfaces by evaluating the external attack surface and full credential lifecycle, specifically identifying vulnerabilities that could lead to large-scale institutional credential leaks on shared devices.

You need to run a full lifecycle credential security audit before publishing new browser extension releases to app stores, or when auditing existing live versions for emerging risks that could expose a large user base to credential theft.
