Two independent\n  regexes in Sniffer._guess_quote_and_delimiter() ran in super-linear time on\n  samples reachable from the public csv.Sniffer.sniff() API (CWE-1176). The\n  quoted-field probe matched a field body with a lazy \".*?\" under re.DOTALL,\n  retrying every closing quote against every later quote in the sample:\n  quadratic. The doubled-quote probe dq_regexp was unanchored, rescanned\n  leading whitespace and ran even when no delimiter had been found, which is\n  exponential on a sample carrying a run of quote characters. Backport of\n  cpython 19e5024518 (gh-109638) and fd78b565 (gh-98820), both in their 3.10\n  form; both are part of Python 3.10.21, the release the CVE record names as\n  fixing the \"0 to < 3.10.21\" range, and gh-98820 alone leaves the\n  doubled-quote probe exponential. The 3.10 variants are required because the\n  3.11+ ones use a possessive quantifier, unsupported by Python 3.8's re module.",

See the tarfile  extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter  for more information. Only Python versions 3.12 or later are affected by these vulnerabilities, earlier versions don't include the extraction filter feature.\n\nNote that for Python 3.14 or later the default value of filter= changed from \"no filtering\" to `\"data\", so if you are relying on this new default behavior then your usage is also affected.\n\nNote that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links.",

See the tarfile  extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter  for more information.\n\nNote that for Python 3.14 or later the default value of filter= changed from \"no filtering\" to `\"data\", so if you are relying on this new default behavior then your usage is also affected.\n\nNote that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process.
