ReDoS: Two separate fixes were needed to eliminate catastrophic backtracking in regexes used for query sanitization, indicating a high risk of denial-of-service via crafted query strings.
Auth Bypass: Upgrading from MSAL v2 to v3 was required to fix authentication bypass vulnerabilities, underscoring the criticality of keeping authentication libraries patched.
