|---|---|---|---|---|---|---|---|
| CVE-2026-18503 | Low | — | < 3.10.21 | 3.10.21 | Aug 10, 2026 | Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff(). | |
| CVE-2026-6879 | Low | — | < 3.10.21 | 3.10.21 | Jul 28, 2026 | `Element.findall()` and fully-consumed `Element.iterfind()` exhibit `O(n^2)` time complexity when using XPath index predicates (e.g. `[1]`, `[last()]`, `[last()-N]`) on XML documents with many same-tag siblings. `Element.find()` is only affected when the first match is near the e | |
| CVE-2026-15308 | Hig | 7.5 | < 3.10.21 | 3.10.21 | Jul 9, 2026 | The incremental HTML parser (html.parser.HTMLParser) allows for CPU denial-of-service through repeated unterminated markup declarations when processing uncontrolled data. | |
| CVE-2026-4360 | Med | 5.3 | >= 0 | — | Jun 30, 2026 | In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks. An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract( | |
| CVE-2026-11972 | Hig | — | < 3.10.21 | 3.10.21 | Jun 23, 2026 | When using the "tarfile" module with a file opened in "streaming mode" (mode="r|") the tarfile module did not properly handle EOF, making archive parsing take exponentially longer. | |
| CVE-2026-0864 | Med | 5.5 | < 3.10.21 | 3.10.21 | Jun 23, 2026 | When using the "configparser" module to write configuration files containing multi-line text values with carriage return characters (\r) the resulting file could be injected with unexpected keys and values if the attacker controls the written value. | |
| CVE-2026-11940 | Hig | — | < 3.10.21 | 3.10.21 | Jun 23, 2026 | tarfile.extractall() with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the | |
| CVE-2026-12003 | Med | — | < 3.11.16 | 3.11.16 | Jun 16, 2026 | To allow builds of Python to be run from an in-tree layout (rather than an installed file layout), the VPATH variable is defined at build time and used to locate certain landmarks - specifically, Modules/setup.local. When this landmark is found relative to VPATH relative to the e | |
| CVE-2026-9669 | Hig | — | < 3.10.21 | 3.10.21 | Jun 8, 2026 | bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to | |
| CVE-2026-7774 | Med | — | < 3.10.21 | 3.10.21 | Jun 4, 2026 | tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall() to write files | |
| CVE-2026-3276 | Med | — | < 3.10.21 | 3.10.21 | Jun 3, 2026 | unicodedata.normalize() can take excessive CPU time when processing specially crafted Unicode input containing long runs of combining characters with alternating Canonical Combining Class values. This affects all normalization forms. | |
| CVE-2026-8328 | Med | — | < 3.10.21 | 3.10.21 | May 13, 2026 | The ftpcp() function in Lib/ftplib.py was not updated when CVE-2021-4189 was fixed. While makepasv() was patched to replace server-supplied PASV host addresses with the actual peer address (getpeername()[0]), ftpcp() still calls parse227() directly and passes the raw attacker | |
| CVE-2026-7210 | Hig | 7.5 | < 3.13.14 | 3.13.14 | May 11, 2026 | `xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying thi | |
| CVE-2026-3087 | Hig | 7.5 | < 3.10.21 | 3.10.21 | Apr 27, 2026 | If `shutil.unpack_archive()` is given a ZIP archive with an absolute Windows path containing a drive (`C:\\...`) then the archive will be extracted outside the target directory which is different than other operating systems. Only Windows is affected by this vulnerability. | |
| CVE-2026-6019 | Med | 6.1 | < 3.13.14 | 3.13.14 | Apr 22, 2026 | http.cookies.Morsel.js_output() returns an inline inside the generated script element. Mitigation base64-encodes the cookie value to disallow esc | |
| CVE-2026-3298 | Hig | — | < 3.11.16 | 3.11.16 | Apr 21, 2026 | The method "sock_recvfrom_into()" of "asyncio.ProacterEventLoop" (Windows only) was missing a boundary check for the data buffer when using nbytes parameter. This allowed for an out-of-bounds buffer write if data was larger than the buffer size. Non-Windows platforms are not affe | |
| CVE-2026-5713 | Med | — | >= 3.14.0, < 3.14.5 | 3.14.5 | Apr 14, 2026 | The "profiling.sampling" module (Python 3.15+) and "asyncio introspection capabilities" (3.14+, "python -m asyncio ps" and "python -m asyncio pstree") features could be used to read and write addresses in a privileged process if that process connected to a malicious or "infected" | |
| CVE-2026-4786 | Hig | 7.1 | < 3.10.21 | 3.10.21 | Apr 13, 2026 | Mitgation of CVE-2026-4519 was incomplete. If the URL contained "%action" the mitigation could be bypassed for certain browser types the "webbrowser.open()" API could have commands injected into the underlying shell. See CVE-2026-4519 for details. | |
| CVE-2026-6100 | Hig | 8.1 | < 3.10.21 | 3.10.21 | Apr 13, 2026 | Use-after-free (UAF) was possible in the `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile` when a memory allocation fails with a `MemoryError` and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The | |
| CVE-2026-3446 | Med | — | < 3.13.13 | 3.13.13 | Apr 10, 2026 | When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other impleme |
