Supply chain provenance
Status for the latest visible version.
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.

Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| semgrep | semgrep:dynamic-require | AI (semgrep): Dynamic require of user-specified files is core to the CoffeeScript CLI runner; not a supply-chain risk for this package. | ai | |
| publish-pattern | new-deps-added | AI (publish-pattern): babel-core is an optional dependency for build tooling in a compiler; not a supply-chain risk vector for this package. | ai | |
| dependencies | unvetted-dep:babel-core | AI (dependencies): babel-core is listed as an optionalDependency for minification tooling in a compiler package; not a true runtime dependency and consistent with legitimate use. | ai | |
| source-diff | obfuscated-file:lib/coffeescript-browser-compiler-modern/coffeescript.js | AI (source-diff): Browser compiler bundle built with webpack+Babel; minified output is expected and documented for this package's ES module browser distribution entry point. | ai | |
| source-diff | net-exec-file:lib/coffeescript-browser-compiler-modern/coffeescript.js | AI (source-diff): CoffeeScript browser compiler legitimately uses XHR to load .coffee scripts and eval/Function() to execute compiled output — core documented functionality. | ai | |
| source-diff | source-size-tripled | AI (source-diff): Size increase is fully explained by addition of two ~525KB webpack browser compiler bundles, a new feature in this version. | ai | |
| source-diff | obfuscated-file:lib/coffeescript-browser-compiler-legacy/coffeescript.js | AI (source-diff): Browser compiler bundle built with webpack+Babel; minified output is expected and documented for this package's browser distribution entry point. | ai | |
| source-diff | net-exec-file:lib/coffeescript-browser-compiler-legacy/coffeescript.js | AI (source-diff): CoffeeScript browser compiler legitimately uses XHR to load .coffee scripts and eval/Function() to execute compiled output — core documented functionality. | ai | |
| source-diff | net-exec-file:lib/coffeescript/browser.js | AI (source-diff): browser.js implements CoffeeScript's browser compilation layer; eval of compiled CoffeeScript is core functionality, not malware. | ai | |
| source-diff | obfuscated-file:lib/coffeescript/parser.js | AI (source-diff): parser.js is generated by jison parser generator, which produces long lines. This is expected for a compiler package and not obfuscation. | ai | |
| source-diff | net-exec-file:lib/coffeescript/command.js | AI (source-diff): command.js is the CoffeeScript CLI tool; child_process usage for spawning compiled scripts is expected and documented behavior. | ai | |
| source-diff | net-exec-file:lib/coffee-script/browser.js | AI (source-diff): browser.js is CoffeeScript's legitimate browser integration; eval(compile(code)) is the intended in-browser compilation feature, not a dropper. Browser API detection triggers false 'network' signal. | ai | |
| source-diff | obfuscated-file:lib/coffee-script/parser.js | AI (source-diff): parser.js is generated by jison parser generator, which produces long-line output (parser tables). This is standard generated code, not obfuscation. | ai | |
| install-scripts | install-script:install | AI (install-scripts): CoffeeScript's documented build flow requires native compilation via sudo bin/cake install; stable for this package. | ai | |
| semgrep | semgrep:eval-usage | AI (semgrep): CoffeeScript's browser.js uses eval() to execute compiled code in the browser — this is the core, documented behavior of a JavaScript transpiler, not a supply-chain risk. | ai | |
| semgrep | semgrep:child-process-import | AI (semgrep): CoffeeScript's CLI uses child_process to spawn subprocesses, which is expected behavior for a compiler's command-line interface. | ai | |
| provenance | no-provenance | AI (provenance): Established package with 73 versions and a verified GitHub repo; lack of Sigstore provenance is common and not a risk signal here. | ai |
