Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

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.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:mscdex-busboy-5a1040d/deps/encoding/encoding-indexes.js AI (source-diff): Vendored encoding-indexes.js contains character encoding lookup tables (large integer arrays) from the Encoding Standard polyfill — not obfuscated code. ai
source-diff obfuscated-file:mscdex-busboy-f70e0dd/deps/encoding/encoding-indexes.js AI (source-diff): WHATWG encoding index data file containing numeric code point arrays for character set mappings; long lines are data, not obfuscation. ai
source-diff encoded-string-file:test/test-types-multipart.js AI (source-diff): Test file contains repeated single-char strings (AAAA…, BBBB…) as mock multipart payloads — not obfuscated code. Stable false positive for busboy. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require loads modules from the package's own local ./types/ directory using __dirname — a standard plugin-loader pattern, not arbitrary code execution. ai
dependencies unvetted-dep:dicer AI (dependencies): dicer is mscdex's own companion package and the canonical multipart stream splitter dependency for busboy; this is expected and benign. ai

v0.3.1

2 findings
HIGH New obfuscated file: mscdex-busboy-5a1040d/deps/encoding/encoding-indexes.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

2 findings
HIGH New obfuscated file: mscdex-busboy-f70e0dd/deps/encoding/encoding-indexes.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

LOW No provenance attestation provenance

v0.1.1

2 findings
HIGH Long encoded string in modified file: test/test-types-multipart.js source-diff

Modified file contains 2 long encoded string(s) (200+ chars). These are commonly used to hide malicious payloads.
