Route DataAccessException and PersistenceException (including bare
ConstraintViolationException) to a unified handler that extracts the
constraint name and returns "Constraint violation: <name>" instead of
the raw PSQLException message. Other DB errors continue to return the
generic "Database error" response.
Adds DaoUtil.extractConstraintViolation helper and an integration test
that verifies no SQL details leak when an FK constraint is violated.
Replace stream().filter().collect() in resolveAll with single-pass loop
to avoid allocations on the common path (nothing blocked). Remove
redundant isEnabled() checks inside the resolver since it is only wired
when SSRF protection is enabled. Add resolveAll test coverage.
Keep both save-time validation (Oauth2ClientDataValidator) and runtime
re-validation as defense-in-depth: DNS records can change between config
save and OAuth2 login, creating a TOCTOU gap.
- Use kebab-case 'report-only' in web-ui configs to match thingsboard.yml
- Add log.warn for unrecognized X-Frame-Options values in customizer
- Replace @Configuration with @Component on HttpSecurityHeadersProperties
- Add comment explaining '!== false' vs truthiness pattern in server.ts
- 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
Fix security issues from penetration test report:
- M2: Add configurable X-Frame-Options and CSP headers (disabled by default)
- L2: Add X-Content-Type-Options and Referrer-Policy headers (enabled by default)
- L3: Make CORS allowed-origin-patterns configurable via TB_CORS_* env vars
Root cause: ThingsboardSecurityConfiguration called .disable() on the entire
HeadersConfigurer, which removed ALL security headers including Cache-Control.
Fix uses defaultsDisabled() + selective header enablement via a new
HttpSecurityHeadersCustomizer component.
Both Spring Boot (tb-node) and Express.js (web-ui) share the same
SECURITY_HEADERS_* environment variables for consistent configuration
across monolith and microservice deployments.
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.
