{"id":"CVE-2025-4435","summary":"Tarfile extracts filtered members when errorlevel=0","details":"When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member would still be extracted and not skipped.","aliases":["BIT-libpython-2025-4435","BIT-python-2025-4435","BIT-python-min-2025-4435","PSF-2025-8"],"modified":"2026-08-12T03:51:17.712657746Z","published":"2025-06-03T12:59:06.792Z","related":["ALSA-2025:10026","ALSA-2025:10031","ALSA-2025:10128","ALSA-2025:10136","ALSA-2025:10140","ALSA-2025:10148","ALSA-2025:10189","ALSA-2025:23530","CGA-g7wf-vxq2-34q4","SUSE-SU-2025:02297-1","SUSE-SU-2025:02359-1","SUSE-SU-2025:02427-1","SUSE-SU-2025:02717-1","SUSE-SU-2025:02767-1","SUSE-SU-2025:02778-1","SUSE-SU-2025:20492-1","SUSE-SU-2025:20539-1","SUSE-SU-2026:0210-1","openSUSE-SU-2025:15289-1","openSUSE-SU-2025:15713-1"],"database_specific":{"cna_assigner":"PSF","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/4xxx/CVE-2025-4435.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/4xxx/CVE-2025-4435.json"},{"type":"ADVISORY","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/MAXIJJCUUMCL7ATZNDVEGGHUMQMUUKLG/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-4435"},{"type":"REPORT","url":"https://github.com/python/cpython/issues/135034"},{"type":"FIX","url":"https://github.com/python/cpython/commit/19de092debb3d7e832e5672cc2f7b788d35951da"},{"type":"FIX","url":"https://github.com/python/cpython/commit/28463dba112af719df1e8b0391c46787ad756dd9"},{"type":"FIX","url":"https://github.com/python/cpython/commit/3612d8f51741b11f36f8fb0494d79086bac9390a"},{"type":"FIX","url":"https://github.com/python/cpython/commit/4633f3f497b1ff70e4a35b6fe2c907cbe2d4cb2e"},{"type":"FIX","url":"https://github.com/python/cpython/commit/9c1110ef6652687d7c55f590f909720eddde965a"},{"type":"FIX","url":"https://github.com/python/cpython/commit/9e0ac76d96cf80b49055f6d6b9a6763fb9215c2a"},{"type":"FIX","url":"https://github.com/python/cpython/commit/aa9eb5f757ceff461e6e996f12c89e5d9b583b01"},{"type":"FIX","url":"https://github.com/python/cpython/commit/dd8f187d0746da151e0025c51680979ac5b4cfb1"},{"type":"FIX","url":"https://github.com/python/cpython/pull/135037"},{"type":"PACKAGE","url":"https://github.com/python/cpython"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"introduced":"b494f5935c92951e75597bfe1c8b1f3112fec270"},{"introduced":"deaf509e8fc6e0363bd6f26d52ad42f976ec42f2"},{"introduced":"0fb18b02c8ad56299d6a2910be0bab8ad601ef24"},{"introduced":"60403a5409ff2c3f3b07dd2ca91a7a3e096839c7"},{"introduced":"b092705907c758d4f9742028652c9802f9f03dd3"},{"fixed":"865270262ade38b96fce88e32a321caac5332a87"},{"fixed":"88663ef89ba3576df02cc818c653f91c7d5dd023"},{"fixed":"498b971ea3673012a1d4b21860b229d55fc6e575"},{"fixed":"55fee9cf216abe4ec0d1139f94b1930fbd0c7644"},{"fixed":"8a526ec7cbea8fafc9dae4b3dd6371906b9be342"},{"fixed":"26d485d12255a10a8e965b561e7d8a70a732ec69"},{"fixed":"19de092debb3d7e832e5672cc2f7b788d35951da"},{"fixed":"28463dba112af719df1e8b0391c46787ad756dd9"},{"fixed":"3612d8f51741b11f36f8fb0494d79086bac9390a"},{"fixed":"4633f3f497b1ff70e4a35b6fe2c907cbe2d4cb2e"},{"fixed":"9c1110ef6652687d7c55f590f909720eddde965a"},{"fixed":"9e0ac76d96cf80b49055f6d6b9a6763fb9215c2a"},{"fixed":"aa9eb5f757ceff461e6e996f12c89e5d9b583b01"},{"fixed":"dd8f187d0746da151e0025c51680979ac5b4cfb1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.9.23"},{"introduced":"3.10.0"},{"fixed":"3.10.18"},{"introduced":"3.11.0"},{"fixed":"3.11.13"},{"introduced":"3.12.0"},{"fixed":"3.12.11"},{"introduced":"3.13.0"},{"fixed":"3.13.4"},{"introduced":"3.14.0a1"},{"fixed":"3.14.0b3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.14.0b2","v3.14.0b1","v3.9.22","v3.13.3","v3.11.12","v3.12.10","v3.10.17","v3.13.2","v3.12.9","v3.13.1","v3.12.8","v3.10.16","v3.11.11","v3.9.21","v3.13.0","v3.12.7","v3.11.10","v3.10.15","v3.12.6","v3.9.20","v3.12.5","v3.12.4","v3.12.3","v3.11.9","v3.10.14","v3.9.19","v3.12.2","v3.11.8","v3.12.1","v3.11.7","v3.11.6","v3.12.0","v3.11.5","v3.9.18","v3.10.13","v3.11.4","v3.10.12","v3.9.17","v3.10.11","v3.11.3","v3.10.10","v3.11.2","v3.10.9","v3.11.1","v3.9.16","v3.11.0rc2","v3.10.8","v3.9.15","v3.9.14","v3.10.7","v3.11.0rc1","v3.10.6","v3.11.0b5","v3.11.0b4","v3.10.5","v3.11.0b3","v3.11.0b2","v3.9.13","v3.11.0b1","v3.11.0a7","v3.10.4","v3.9.12","v3.9.11","v3.10.3","v3.11.0a6","v3.11.0a5","v3.11.0a4","v3.10.2","v3.11.0a3","v3.10.1","v3.9.9","v3.9.8","v3.10.0rc2","v3.9.7","v3.10.0rc1","v3.10.0b4","v3.9.6","v3.10.0b3","v3.10.0b2","v3.10.0b1","v3.9.5","v3.10.0a7","v3.9.2","v3.9.2rc1","v3.10.0a1","v3.9.0b5","v3.9.0b3","v3.9.0b1","v3.9.0a2","v3.7.0a2","v3.6.0b1","v3.6.0a3","v3.5.0b1","v3.5.0a4","v3.5.0a3","v3.5.0a2","v3.5.0a1","v3.4.0b3","v3.4.0b2","v3.4.0b1","v3.4.0a4","v3.4.0a3","v3.4.0a2","v3.4.0a1","v3.3.0rc3","v3.3.0rc2","v3.3.0rc1","v3.3.0b2","v3.3.0b1","v3.3.0a4","v3.3.0a3","v3.3.0a2","v3.2rc3","v3.2rc2","v3.2rc1","v3.2b2","v3.2b1","v3.2a4","v3.2a3","v3.2a2","v3.2a1","v3.1","v3.1rc2","v3.1rc1","v3.1b1","v3.1a2","v
