Detailsinfo

A vulnerability was found in HMBRAND Text::CSV_XS up to 1.61 on Perl. It has been rated as critical. This issue affects the function after_parse/before_print/on_error. The manipulation with an unknown input leads to a expired pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-825. The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption. The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead. Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected.

The weakness was released by Leon Timmermans as c17f31a5f2bf36674748eb4b6e25672f0571a224. The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-7111 since 04/26/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.
