- CVE-2026-3219: pip doesn't reject concatenated ZIP (bsc#1262429 bsc#1262467).
- CVE-2026-3276: quadratic complexity in `unicodedata.normalize()` can lead to DoS when processing specially crafted Unicode input (bsc#1267581).
- CVE-2026-3446: Base64 decoding stops at first padded quad by default (bsc#1261970).
- CVE-2026-3479: python: improper resource argument validation can allow path traversal (bsc#1259989).
- CVE-2026-4224: C stack overflow when parsing XML with deeply nested DTD content models (bsc#1259735).

- CVE-2026-6357: pip self-update functionality can import newly installed modules after wheel installation (bsc#1263442 bsc#1263443).
- CVE-2026-6879: quadratic behavior in `xml.etree.ElementPath` index predicates can lead to a denial of service via high CPU usage (bsc#1273148).
- CVE-2026-7210: `xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash- flooding protection (bsc#1264962).
- CVE-2026-7774: `tarfile.data_filter` path traversal bypass allows writing outside the extraction directory (bsc#1267821).
- CVE-2026-8328: `ftpcp()` does not use actual peer address and trusts server-supplied PASV host address (bsc#1265268).
- CVE-2026-8643: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite (bsc#1266669).
- CVE-2026-9669: crafted input can cause a stack buffer overflow (bsc#1267974).
- CVE-2026-11940: tarfile extraction filter bypass via a crafted archive allows escaping the destination directory and enables arbitrary file reads and writes (bsc#1268977).
- CVE-2026-11972: infinite loop due to improper EOF handling in the tarfile module streaming mode can lead to DoS (bsc#1269788).
- CVE-2026-13346: Arbitrary file installation via malicious package indexes (bsc#1273090 bsc#1273091 bsc#1273094).
- CVE-2026-15308: Incremental HTMLParser allows CPU-exhaustion DoS via repeated unterminated markup declarations (bsc#1271192).
- CVE-2026-15310: memory exhaustion in zipfile in bzip2/LZMA/Zstandard decompression (bsc#1277111).
- CVE-2026-15806: urllib.request.HTTPPasswordMgr credentials for one URL scheme sent over another scheme (bsc#1276223).
- CVE-2026-17084: StringPrep algorithm considered Unicode codepoint attributes outside Unicode 3.2.0 (bsc#1276226).
- CVE-2026-18503: attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU (bsc#1274683).
- CVE-2026-19672: tarfile extraction filter bypass allows creation of directories outside the destination (bsc#1276227).
- CVE-2026-82049: tarfile extraction filters mishandle archives containing a hard link to a symbolic link, allowing file modification and content disclosure (bsc#1280459).

Non security issue fixed:

- Fix an error that returned non-zero exit status 1 (bsc#1277271).
- Fix regression in `http.cookies` (bsc#1263083).
- Update bundled pip wheels to pip-20.0.2-py2.py3-none-any.whl.
