What our analysis found

Sapper - MineSweeper classic game, used by 1,000 people, is rated caution by Extension Auditor. Our code review reported 2 findings (2 medium), led by other. It comes from a trusted publisher and was last updated in September 2026.

Key findings

  • Medium

    Other

    On every extension update, the background script forcibly opens a new active tab to `custom-cursor.world` — a site completely unrelated to the Minesweeper game and not disclosed in the CWS listing, privacy policy, or data-collection declarations. This is unwanted behavior: users never consented to having their browser navigate to a third-party site each time the extension updates. The install-time redirect to `[domain withheld]` and the UTM-tagged uninstall URL indicate this extension is part of an network.

  • Medium

    Other

    The manifest declares `unsafe-eval` in the isolated world CSP despite the extension having no content scripts whatsoever — making this policy meaningless for its stated purpose but potentially a forward-compatibility stub for a future malicious update that injects and eval's code in page contexts. A simple popup-only game has no legitimate need for `unsafe-eval` anywhere in its CSP.

Analyst notes

The game logic in is clean — a straightforward Minesweeper implementation with no data exfiltration, no network calls, and no abuse of permissions. However, silently opens a tab to `custom-cursor.world` on every extension update — a site entirely unrelated to the game and not disclosed anywhere in the CWS listing or privacy policy. This is classic behavior. The publisher reputation (60% malicious rate across their other 5 extensions) strongly corroborates that this extension is part of a coordinated low-trust publisher network, not a false positive. The third-party risk score ( impact) reflects the lack of permissions but cannot capture this behavioral pattern.
