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.\n\nCalling 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."}], "lastModified": "2026-06-25T20:17:17.543", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:hmbrand:text\\:\\:csv_xs:*:*:*:*:*:perl:*:*", "vulnerable": true, "matchCriteriaId": "42D9FCD4-72E4-4E7D-B842-1DF319D08DF0", "versionEndExcluding": "1.62"}], "operator": "OR"}]}], "sourceIdentifier": "9b29abf9-4ab0-4765-b253-1875cd9b441e"}
