Ordered by severity, then signals introduced in this release. Hidden characters are shown as ⟨U+…⟩.

  1. info warn → info by review encoding-base64 test/subresource-integrity/GHSA-f72v-6w45-q472.js:12:18 new in this release

    base64-like blob (44 bytes, compression ratio 1.25) (raw pass, confidence 0.60)

    const skip = runtimeFeatures.has('crypto') === false
    const hash256 = 'wFNeS+K3n/2TKRMFQ2v4iTFOSj+uwF7P/Lt98xrZ5Ro='
    
    test('should ignore well-formed but unknown algorithm tokens', { skip }, (t) => {
    dismissed LLM, confidence 0.93 A base64 SHA-256 digest constant in an SRI regression test.
    Reasoning

    A base64 SHA-256 digest assigned to a constant in a regression test for a subresource integrity advisory. The test uses it to check handling of unknown algorithm tokens. The value is ordinary test data.

  2. info warn → info by review encoding-base64 test/subresource-integrity/GHSA-f72v-6w45-q472.js:25:20 new in this release

    base64-like blob (44 bytes, compression ratio 1.25) (raw pass, confidence 0.60)

      const body = 'Hello world!'
      const hash256 = 'wFNeS+K3n/2TKRMFQ2v4iTFOSj+uwF7P/Lt98xrZ5Ro='
      const hash384 = 'hiVfosNuSzCWnq4X3DTHcsvr38WLWEA5AL6HYU6xo0uHgCY/JV615lypu7hkHMz+'

    likely benign LLM, confidence 0.97 Base64 SRI digest constants in a test fixture.
    Reasoning

    These are SRI hash strings (base64 digests of 'Hello world!') in a test file for subresource integrity. Raw pass base64 heuristic is a known false-positive source here.

  3. info warn → info by review encoding-base64 test/subresource-integrity/GHSA-f72v-6w45-q472.js:26:20 new in this release

    base64-like blob (64 bytes, compression ratio 1.17) (raw pass, confidence 0.60)

      const hash512 = '9s3ioPgZMUzd5V/CJ9jX2uPSjMVWIioKitZtkcytSq1glPUXohgjYMmqz2o9wyMWLLb9jN/+2w/gOPVehf+1tg=='
    likely benign LLM, confidence 0.97 Base64 SRI sha256 digest constant in a test fixture.
    Reasoning

    Same SRI hash constant block in a Node.js fetch integrity test; expected digest values, not obfuscated payloads.

  4. info warn → info by review encoding-base64 test/subresource-integrity/GHSA-f72v-6w45-q472.js:27:20 new in this release

    base64-like blob (88 bytes, compression ratio 1.12) (raw pass, confidence 0.60)

      const hash384 = 'hiVfosNuSzCWnq4X3DTHcsvr38WLWEA5AL6HYU6xo0uHgCY/JV615lypu7hkHMz+'
      const hash512 = '9s3ioPgZMUzd5V/CJ9jX2uPSjMVWIioKitZtkcytSq1glPUXohgjYMmqz2o9wyMWLLb9jN/+2w/gOPVehf+1tg=='
    
      const server = createServer({ joinDuplicateHeaders: true }, (req, res) => {
    likely benign LLM, confidence 0.97 Base64 SRI sha384 digest constant in a test fixture.
    Reasoning

    SRI sha384 digest string used as a test expectation for integrity checking; legitimate test data.

    likely benign LLM, confidence 0.97 Test fixture containing intentionally wrong base64 SRI hash strings.
    Reasoning

    These are hash digest test fixtures in a subresource-integrity test file. Base64 SRI hashes are expected here, and the raw pass flags them only because they look base64-like. No execution or decoding occurs.

  14. info warn → info by review encoding-base64 test/subresource-integrity/GHSA-f72v-6w45-q472.js:106:25 new in this release

    base64-like blob (88 bytes, compression ratio 1.12) (raw pass, confidence 0.60)

      const hash384Wrong = 'zxSYGGGjWi7iIZ9SmiTenQIQ+/nzPTd5bbesJhBTZvoYomj28rsVLXbUyJU/Yqob'
      const hash512Wrong = 'eC9loL1pd8AD1Btp9aHu+ymH5Rfnh64hiTYgyfeXy270KfjPQupBkhb2OeP35vZA8ofSBNJ01LzweDIhznuqaw=='

    likely benign LLM, confidence 0.93 Base64-encoded PNG image embedded as a test fixture in busboy's multipart parser tests.
    Reasoning

    Raw-pass base64 hit inside a test fixture. The blob decodes to a PNG header (iVBORw0KGgo), which fits a multipart upload test embedding an image. Raw findings have a high false-positive rate, and this is ordinary test data.

  19. info warn → info by review encoding-base64 test/busboy/test-parser.js:188:1

    base64-like blob (940 bytes over 13 lines, compression ratio 0.79) (raw pass, confidence 0.60)

    likely benign LLM, confidence 0.93 Another base64 PNG image fixture in the busboy multipart test suite.
    Reasoning

    Same PNG base64 fixture pattern as the other hits in this file, used as multipart test input for the busboy parser. No execution or decoding of the data into anything dangerous is visible.

  20. info warn → info by review encoding-base64 test/busboy/test-parser.js:254:1

    likely benign LLM, confidence 0.93 Base64-encoded image data as a multipart test fixture.
    Reasoning

    Base64 blob with PNG content, located in the busboy test suite. Entropy and compression ratio are typical of compressed image data, so the flag is a false positive on a raw pass.

    likely benign LLM, confidence 0.92 Base64-encoded multipart form body with an embedded PNG file, used as a parser test fixture.
    Reasoning

    Snippet begins with base64 for a multipart boundary and Content-Disposition headers (LS0tLS0t is '-----', and the decoded text is form-data headers) followed by an embedded PNG. This is a multipart request body fixture for testing file uploads.
