Text::CSV_XS versions before 1.65 for Perl read before the start of an all-blank field under allow_whitespace in strip_trail_whitespace.

Under allow_whitespace, strip_trail_whitespace removes trailing spaces and tabs from each unquoted field without stopping at the start of the field. For a field of only blanks it reads the byte before the field's heap buffer. If that byte is also a space or tab, it may be zeroed and the walk continue backwards, depending on what the allocator placed there.

Leading blanks are normally skipped before a field is stored, but an all-blank field still arrives after a leading escape_char that differs from quote_char, or as a quoted field in getline when its line ends in two CRs.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
