Release Notes

mongodb/kingfisher (mongodb/kingfisher)

v2.0.0

Compare Source

• Added Kingfisher-side typed validation for Betterleaks' generic-credential-uri rule without
  changing its detector: PostgreSQL, MySQL/MariaDB, and MongoDB URI captures now use the
  corresponding live validator and feed validated credentials into blast-radius mapping, while
  unsupported URI schemes remain detected with validation not attempted. JDBC strings containing
  a credential-bearing PostgreSQL/MySQL URI are handled through that inner URI, and direct
  CredentialUri validation also dispatches supported jdbc: inputs.
• Removed the Veles Paystack, PyPI, and Square OAuth application-secret adapters. PyPI upload-token and Square access-token detection remain covered by Betterleaks; Paystack and Square OAuth application-secret built-in coverage are no longer included.
• Security: the MongoDB, MySQL, Postgres, and JDBC validators now enforce the same SSRF gate as the HTTP/gRPC/JWT validators. Previously they only rejected loopback/unspecified hosts, so a crafted connection string in scanned content could make Kingfisher open TCP connections to RFC1918, link-local (including 169.254.169.254), CGNAT, and other non-public addresses, turning the scan report into an internal-network reachability oracle. Every host in a Postgres multi-host URL and every MongoDB seed — including hosts resolved via mongodb+srv:// SRV records — is now checked, and blocked targets report a constant message instead of the driver's connection error. Use --allow-internal-ips to opt back in.
• Breaking (library): validate_mongodb, validate_mysql, validate_postgres, and validate_jdbc take an additional allow_internal_ips: bool argument.
• Restored per-rule tls_mode for built-in rules. The imported-rule capability overlay now accepts tls_mode: strict | lax | off, and betterleaks.mongodb-connection-string and betterleaks.jwt declare lax so self-managed clusters and self-hosted IdPs presenting private-CA or self-signed certificates validate again. This remains opt-in on both sides: it takes effect only when the operator also runs --tls-mode lax (or --tls-mode off). The build rejects an unknown tls_mode value, or a tls_mode on a rule with no validator.
• Kingfisher 1.x rule selectors keep working. --rule, --exclude-rule, and rules.disabled entries naming kingfisher.* IDs now resolve to their 2.x replacements through a new alias table, with a one-time deprecation warning naming the selector to migrate to, instead of failing the scan. Exact kingfisher.* IDs still win when the 1.x catalog is loaded via --rules-path, and an unknown kingfisher.* selector is still an error.
• Added a rule-coverage drift guard. crates/kingfisher-rules/data/legacy-rule-aliases.yml maps
  migrated Kingfisher 1.x families with known 2.x replacements, and a test asserts each alias target
  still resolves against the built-in catalog, so an upstream release that drops a replacement fails
  the build instead of silently breaking that compatibility path.
• Restored scan-time access mapping for validated Veles rules (Slack app-level/config tokens, DigitalOcean, SendGrid), which previously reached the rule-ID dispatch and matched nothing.
• Breaking: moved the candidate detector catalog to the Betterleaks rule format, with selected
  Veles detectors filling gaps, giving the community a well-designed shared format and a common
  place to develop generally useful rules.
• Kingfisher now fetches and parses the Betterleaks catalog and selected Veles source files at build
  time; the Kingfisher 1.x YAML custom-rule format remains supported for custom rules.
• Preserved Kingfisher's engine capabilities around validation, blast-radius mapping, and credential revocation while allowing us to focus investment on scan performance, integrations, and analysis workflows.
• All rules now use Vectorscan candidate detection, eliminating unconditional whole-blob regex fallbacks for Betterleaks' large generic credential patterns; Betterleaks path and finding-filter regex helpers are also compiled once with Vectorscan instead of being rebuilt per path or finding.
