CVE-2026-14740: Perl Dbi

Critical severity, CVSS 9.1. EPSS: 0.4% chance of exploitation in the next 30 days.

DBI versions before 1.650 for Perl read one byte out-of-bounds in preparse when deleting an initial SQL comment. The preparse method normalises SQL and removes comments. When the SQL starts with a comment line, the deletion of that line during normalisation led to an out-of-bounds read by one byte. The result is a fault on memory-hardened builds and nondeterministic newline retention on normal builds.

Affected products

• Perl Dbi: before 1.650 (fixed in 1.650)
