In code review (v4.1.5.0)

Our reviewer read version 4.1.5.0 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

LockSelf, used by 50,000 people, showed no malicious code in Extension Auditor's review. Our code review reported 1 finding (1 high), led by other. Its permissions mean it can read and change data on all websites.

Key findings

high· other —The bundled manifest lists only 6 permissions, while the published CWS manifest summary includes 4 additional permissions: activeTab, webRequest, scripting, and alarms. Such a mismatch for the same version () could indicate a silent update or misrepresentation and should be investigated.

The extension is a legitimate professional password manager (ANSSI‑certified). All observed code handles credential detection, local crypto, and first‑party API sync as expected. The ML model likely overfitted on large JS bundles (libsodium), necessary broad permissions, and network patterns normal for password managers. However, the bundled manifest omits four permissions present in the live CWS listing (webRequest, scripting, alarms, activeTab), which introduces uncertainty; the publisher’s other extension is flagged malicious, but no malicious behavior was found in this codebase.

Item	Type	Severity	Description
privacy	Permission	Critical	This permission allows modification of Chrome's privacy settings. Rated Critical because it can disable security features, modify network configurations, and compromise browser security settings.
<all_urls>	Host	Critical	Broad host access — the extension can read/modify content on every website.
webNavigation	Permission	High	This permission enables monitoring of all browser navigation events and transitions. Rated High because it can track every page visit, navigation method, and browsing pattern, potentially exposing sensitive browsing behavior and user activities.
identity	Permission	High	This permission accesses Chrome identity service and user information. Rated High because it can obtain OAuth tokens, access connected accounts, and impersonate the user in authenticated service.
Contextual Risk Factors	Risk Factor	High	The following context increases the overall risk: • 10% increase: Early script execution enables pre-emptive content manipulation • 25% increase: Unsafe code evaluation capabilities increase attack surface
Broad Host Permissions	Risk Factor	High	This extension has broad host permissions allowing it to access many or all websites.
Unsafe WebAssembly Execution	Risk Factor	High	This extension's CSP allows "wasm-unsafe-eval".
storage	Permission	Medium	This permission allows storing data locally in the browser. Rated Medium because it can persist sensitive user data, track user activities over time, and potentially store malicious payloads.
tabs	Permission	Medium	This permission enables tab management and monitoring. Rated Medium because it can track open tabs, access tab metadata, and monitor user browsing patterns.
Early Content Script Execution	Risk Factor	Medium	This extension runs content scripts at document_start.
alarms	Permission	Low	This permission schedules periodic tasks. Rated Low because it can only trigger events at specified times without access to sensitive data.
contextMenus	Permission	Low	This permission adds items to browser context menus. Rated Medium because it only modifies right-click menus without access to page content.

Utilisatrice de la solution dans mon cadre professionnel, je tiens à saluer le gap franchi par LockSelf. Depuis les dernières mises à jour de l'application et du plugin Chrome, l'outil est devenu d'une fluidité absolue. L'auto-remplissage est ultra-performant, rapide, et l'extension est devenue un vrai plaisir à utiliser au quotidien. Quel confort de pouvoir allier la force d'une sécurité souveraine française avec une expérience utilisateur aussi plaisante ! Je recommande sans hésiter.
