// 7 advisories GHSA-4rch-2fh8-94vw Versions of the package mysql2 before 3.9.7 are vulnerable to Arbitrary Code Injection due to improper sanitization of the timezone parameter in the readCodeFor function by calling a native MySQL Server date/time function. CRIT GHSA-fpw7-j2hg-69v5 Versions of the package mysql2 before 3.9.4 are vulnerable to Remote Code Execution (RCE) via the readCodeFor function due to improper validation of the supportBigNumbers and bigNumberStrings values. CRIT GHSA-3f6p-5ww8-9rcr A rogue MySQL server (or MITM) can force mysql2 to send credentials in plaintext by requesting an auth switch to mysql_clear_password. The driver complies without verifying that TLS is active. HIGH GHSA-pmh2-wpjm-fj45 Versions of the package mysql2 before 3.9.8 are vulnerable to Prototype Pollution due to improper user input sanitization passed to fields and tables when using nestTables. HIGH GHSA-rgwj-5xj2-c3m3 File: lib/compressed_protocol.js MODE GHSA-49j4-86m8-q2jw Versions of the package mysql2 before 3.9.4 are vulnerable to Prototype Poisoning due to insecure results object creation and improper user input sanitization passed through parserFn in text_parser.js and binary_parser.js. MODE GHSA-mqr2-w7wj-jjgr Versions of the package mysql2 before 3.9.3 are vulnerable to Improper Input Validation through the keyFromFields function, resulting in cache poisoning. An attacker can inject a colon : character within a value of the attacker-crafted key. MODE Versions of the package mysql2 before 3.9.7 are vulnerable to Arbitrary Code Injection due to improper sanitization of the timezone parameter in the readCodeFor function by calling a native MySQL Server date/time function.
