CVE-2026-88816: DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName

CVE-2026-88816 affects Perl's DBI module in versions before 1.654, where numeric values are incorrectly treated as strings in the FetchHashKeyName feature. The vulnerability allows unintended behavior when fetching database results into hash structures with numeric keys.

Why it matters: Perl developers using DBI to fetch query results into hashes must upgrade to version 1.654 or later to prevent type handling errors that could affect application logic or data integrity.
