Why it matters

CVE-2026-110753 is a use-after-free vulnerability in Text::CSV_XS that can lead to crashes or unexpected behavior. Defenders should verify the version in use and apply the patch or update to version 1.65 or later.

• Potential crashes or unexpected behavior due to use of freed memory
• Need to verify version of Text::CSV_XS in use and apply patch or update
• Possible data corruption or security issues if vulnerability is exploited

Technical summary

The vulnerability occurs when skip_empty_rows skips an empty line in getline with bind_columns, causing the parser to free the current field scalar without checking whether it is bound. This can lead to a crash when later code uses the freed memory. The vulnerability affects Text::CSV_XS versions from 1.46 before 1.65 for Perl, and defenders should verify the version in use and apply the patch or update to version 1.65 or later to mitigate the vulnerability. The vulnerability can be triggered when the parser encounters an empty line in getline with bind_columns, which can cause the parser to free the current field scalar without checking whether it is bound.
