Enhancements
Oracle Masking Stability Improvements
OneDB v2.3.1 improves Oracle masking stability, especially when Oracle SQL Developer or similar Oracle client tools are used to browse table data.
This release improves how OneDB handles Oracle result-set rows that may arrive in fragmented or sparse response formats.
Safer Single Protected-Column Handling
The Oracle masking engine now handles single protected-column scenarios more safely.
This helps prevent cases where masking could behave inconsistently when a query result contains only one protected column.
Improved Credit Card Masking Validation
Credit card masking detection has been strengthened with stricter validation for digit-only card-like values.
This helps reduce incorrect masking behavior for values that should not be treated as credit card numbers.
Bug fixes
- Fixed an Oracle masking issue where the last row in a result set could remain unprotected in certain response formats.
- Fixed masking inconsistency for
SELECT *queries with a single protected column. - Improved Oracle result-set handling for fragmented or sparse response data.
- Improved validation to reduce incorrect or random masking behavior.
Security Updates
Oracle response masking has been improved to reduce the risk of protected field values being displayed unmasked in specific Oracle result-set scenarios.
Known Notes
Query Whitelist behavior remains unchanged.
Whitelisted Oracle queries will continue to bypass response masking as configured.
This release is recommended for customers using Oracle masking with SQL Developer or similar Oracle client tools.
Summary
OneDB v2.3.1 is a patch release focused on Oracle masking stability.
This release improves Oracle result-set handling, fixes a last-row masking issue, strengthens single protected-column handling, and improves credit card masking validation.
