Oct 1, 2024October 2024: Focused on security hardening and robustness of user query handling in prestodb/presto. Delivered two core initiatives: (1) Upgrade hashing from MD5 to SHA-256 across Presto cache and HDFS to harden cache keys and class naming, reducing vulnerability surface. (2) Migrate query state info resource to the re2j regex library for user query pattern matching, with tests ensuring coverage of common and unsupported syntax. These changes improve data integrity, security posture, and robustness of query filtering, with minimal risk of regressions due to targeted changes.
