The flagged value is a 44-byte base64 string used as a Subresource Integrity SHA-256 digest in a fetch integrity test. Such digests are high-entropy by nature and are expected in test fixtures. The raw pass has a high false-positive rate for this pattern.

The same SRI hash literal as the other integrity test cases, used to check fetch integrity verification against a known body. It is a legitimate test fixture.
-

-

A base64 SHA-384 integrity string passed to fetch in a rejection test. The test asserts that a mismatched hash is rejected, which is a normal correctness check.

An 88-byte base64 SHA-512 digest of the test body, consistent with the other multi-algorithm integrity fixtures.
-

A deliberately mismatched SHA-512-labelled integrity value used in a rejection test. This is standard negative-test data.

The base64 flag is on a SHA-256 digest literal in a multi-hash test table. The adjacent 'ä' value in sha384 is an odd non-ASCII character that a reviewer might look at, but it sits in test data and does not form a payload or execution path.

// and no other properties are added to globalThis by undici.install(). const proxyGlobalThis =likely benign A Proxy on globalThis in a test that checks undici.install() does not pollute the global object.Reasoning
The file is undici's test for install(). The Proxy wraps globalThis only to detect unexpected global property writes. The set trap checks against a list of expected exports, and the comment says no other globals are added. It is a verification harness, not a hijack, although the critical severity reflects the Proxy-on-global pattern.

Known SHA-512 digest literal used as a test vector for SRI algorithm handling. Not executed or decoded to a payload.
-
likely benign Base64 string with padding used in a string-match test.
Reasoning
Base64 string literals used to test a case-sensitive string comparison with and without padding. Test data with no decoding or execution.
-
const actualValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs' const expectedValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs=' t.. })likely benign Base64 string literal used in a padding-mismatch test case.Reasoning
Padded and unpadded base64 literals used as comparison inputs in a unit test for caseSensitiveMatch.
-
const actualValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs' const expectedValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs==' t.. })likely benign Base64 string with double padding used as a test value.Reasoning
Double-padded base64 literal used as a test input for string comparison. Ordinary test fixture.
-
likely benign Base64 string literal used in an identical-match test case.
Reasoning
Identical base64 literals in a test of matching strings. No malicious behavior is present.
-
const actualValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs=' const expectedValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs=' t.. })likely benign Base64 string literal used as the expected value in a match test.Reasoning
Repeated padded base64 literal used as the expected value in a unit test. Benign test data.
-
likely benign Double-padded base64 literal used in a matching test.
Reasoning
Double-padded base64 literal used in a matching-strings test. Benign test fixture flagged by a raw-pass heuristic.
-
const actualValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs==' const expectedValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs==' t.. })likely benign Base64 test fixture string used as an SRI hash value in a unit test.Reasoning
Raw pass base64 heuristic firing on a literal test vector used to compare hash strings in a unit test; the file is a standard test for SRI case-sensitive matching, so the blob is expected test data.
-
likely benign Base64 test fixture with invalid padding used to check strict hash comparison.
Reasoning
Same literal test vector reused in a deliberately malformed-padding test case; the raw base64 match is a false positive on test data in a subresource-integrity library's test suite.
-
const actualValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs==' const expectedValue = 'ypeBEsobvcr6wjGzmiPcTaeG7/gUfE5yuYB3ha/uSLs===' t.. })likely benign Base64 test fixture used in a negative assertion for SRI matching.Reasoning
Repeats the malformed-padding test vector in an assertion; no execution or obfuscation involved, just encoded test data in a library's test file.

Comment states these are hash values generated for 'Hello world!'; they are documented SHA-256 digests in a parser test, a legitimate pattern for SRI metadata tests.

SHA-384 test digest in a metadata parsing test with a comment identifying its origin; standard fixture data, no malicious indicator.

SHA-512 test digest in the same test fixture block for SRI parsing; legitimate test data flagged only by the raw base64 heuristic.
