blanket — Greenflagged

seamless js code coverage

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
source-diff	net-exec-file:src/blanket_browser.js	AI (source-diff): blanket_browser.js is the browser adapter for the blanket coverage library; _loadFile loads user-configured adapters/loaders, not external malicious payloads. This is documented library behavior.	ai	2026/04/24
phantom-deps	phantom-dep:requirejs	AI (phantom-deps): requirejs is a legitimate runtime dependency used as a module loader, referenced in config rather than directly imported in source.	ai	2026/04/24
source-diff	obfuscated-file:test/vendor/coffee-script.js	AI (source-diff): File is the well-known CoffeeScript compiler v1.5.0 minified bundle, included as a test vendor dependency. Not malicious obfuscation.	ai	2026/04/24
source-diff	net-exec-file:test/vendor/coffee-script.js	AI (source-diff): CoffeeScript compiler uses eval() to run compiled code and has URL references in comments. Not a dropper/loader — this is standard compiler behavior in a test vendor file.	ai	2026/04/24
semgrep	semgrep:eval-usage	AI (semgrep): eval() in blanket_browser.js executes a user-supplied callback string — expected behavior for a code coverage/instrumentation tool. Not a supply-chain risk.	ai	2026/04/24
source-diff	net-exec-file:test/usage/underscore.js	AI (source-diff): File is the canonical Underscore.js 1.4.3 library added as a test fixture. The detected patterns are standard Underscore internals, not malware. Stable false positive for this package.	ai	2026/04/24
semgrep	semgrep:dynamic-require	AI (semgrep): Dynamic require is used to load a user-configured loader (e.g. CoffeeScript). This is a documented extensibility feature of blanket, not a security risk.	ai	2026/04/24
source-diff	obfuscated-file:dist/mocha/blanket_mocha.js	AI (source-diff): blanket ships browser-targeted bundled dist files as part of its normal release artifacts; long lines are minification, not obfuscation. The bundle header confirms legitimate open-source content.	ai	2026/04/24
