- Extract shared parseHostEntries() to deduplicate setAllowedHosts/setAdditionalBlockedHosts
- Add isHostnameAllowed() and propagate hostname allow-list check in resolver
- Move OAuth2 custom mapper URL SSRF validation to save-time (Oauth2ClientDataValidator)
- Remove runtime SSRF checks from CustomOAuth2ClientMapper and GithubOAuth2ClientMapper
(custom URL now validated at save; GitHub emailUrl is server config, not user input)
- Replace example.com with 8.8.8.8 in resolver test to avoid DNS dependency
Add SsrfSafeAddressResolverGroup that validates resolved IPs at Netty
connection time, eliminating the TOCTOU gap where DNS rebinding domains
resolve to safe IPs during validation but to private/metadata IPs at
connection time. Disable HTTP redirects in TbHttpClient to prevent
redirect-based SSRF bypass.
Add allow-list support (SSRF_ALLOWED_HOSTS) to SsrfProtectionValidator
so customers with IoT devices on private networks can whitelist specific
addresses or CIDR ranges while keeping SSRF protection enabled.
Add SSRF validation to MS Teams webhook, custom OAuth2 mapper, and
GitHub OAuth2 mapper endpoints. Log a warning when SSRF protection is
disabled.
Tests that read shared static state (e.g. testAllowedUrls with 8.8.8.8)
could run concurrently with tests that mutate it (e.g. testAdditionalBlockedSingleIp),
causing intermittent failures. Class-level @ResourceLock serializes all tests.

Move TestDbCallbackExecutor from rule-engine test sources to
common/util main sources as DirectListeningExecutor, making it
available to all modules. Convert to an enum singleton since the
executor is stateless. Widen JpaAbstractDaoListeningExecutorService
service field type from JpaExecutorService to ListeningExecutor to
allow injecting DirectListeningExecutor in tests. Fix
AbstractChunkedAggregationTimeseriesDaoTest NPE by injecting the
direct executor into the spy.
