Security Review

Scope

Project:

Opera Cache Cleaner

Reviewed version or commit:

1.0.0 local workspace

Code Patterns Checked

• No eval.
• No dynamic Function constructor.
• No unsafe HTML injection found in the reviewed code.
• No shell execution.
• No external network calls.
• No secrets committed in the current source files.
• No unsafe file writes. Browser data changes are limited to cache removal.

Dependency Review

Command:

No dependency audit command exists because the project has no package manifest or external dependencies.

Result:

Not applicable.

Runtime Review

• Manifest uses least-privilege permissions for the current feature set.
• No host permissions are declared.
• Local storage is used only for selected range, timer settings, and last run timestamp.
• Cache clearing uses chrome.browsingData.remove({ since }, { cache: true }).

Release Notes

Known residual risks:

No automated browser-extension integration tests exist. Perform an unpacked-extension smoke test in Opera before release.
