CVE-2026-9698 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. DBI versions before 1.648 for Perl saved errors in a limited-sized buffer. Error messages that were returned when RaiseError, PrintError or HandleError were set were written to a 200-byte buffer without a length limit. Attackers that can influence the error text in an application can trigger a buffer overflow.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
