The trust-boundary-violation query only recognized OWASP ESAPI validators
as sanitizers. ESAPI is rarely used in modern Java projects, while regex
validation via String.matches() and @javax.validation.constraints.Pattern
is the standard approach in Spring/Jakarta applications.
RegexpCheckBarrier already exists in Sanitizers.qll and is used by other
queries (e.g., RequestForgery). This wires it into TrustBoundaryConfig,
so patterns like input.matches("[a-zA-Z0-9]+") and @Pattern annotations
are recognized as sanitizers, consistent with the existing ESAPI treatment.
The sensitive-log query (CWE-532) lacked sanitizers for hashed or
encrypted data, while the sibling cleartext-storage query (CWE-312)
already recognized methods with "encrypt", "hash", or "digest" in their
names as sanitizers (CleartextStorageQuery.qll:86).
This adds an EncryptionBarrier to SensitiveLoggingQuery that applies the
same name-based heuristic, making the two queries consistent. Calls like
DigestUtils.sha256Hex(password) or hashPassword(secret) are no longer
flagged when their results are logged.
PathNormalizeSanitizer recognized Path.normalize() and
File.getCanonicalPath()/getCanonicalFile(), but not Path.toRealPath().
toRealPath() is strictly stronger than normalize() (resolves symlinks
and verifies file existence in addition to normalizing ".." components),
and is functionally equivalent to File.getCanonicalPath() for the NIO.2
API. CERT FIO16-J and OWASP both recommend it for path traversal defense.
This adds toRealPath to PathNormalizeSanitizer alongside normalize,
reducing false positives for code using idiomatic NIO.2 path handling.
The java/tainted-arithmetic query now recognizes when an arithmetic
expression appears directly as an operand of a comparison (e.g.,
`if (off + len > array.length)`). Such expressions are bounds checks,
not vulnerable computations, and are excluded via the existing
overflowIrrelevant predicate.
Add test cases for bounds-checking patterns that should not be flagged.
- Model Signature.getInstance() as CryptoAlgoSpec sink (previously only
Signature constructor was modeled)
- Add HMAC-based algorithms (HMACSHA1/256/384/512, HmacSHA1/256/384/512)
and PBKDF2 to the secure algorithm whitelist
- Fix XDH/X25519/X448 tests to use KeyAgreement.getInstance() instead of
KeyPairGenerator.getInstance() to match their key agreement semantics
- Add test cases for SHA384withECDSA, HMACSHA*, and PBKDF2WithHmacSHA1
from user-reported false positives
- Update change note to document all additions
