| CVE | Description | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|
| CVE-2026-4786 | 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. | 7.0 | 0.29% | 2026-04-13 | 2026-07-06 |
| CVE-2026-3644 | The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The Morsel.update(), |= operator, and unpickling paths were not patched, allowing control characters to bypass input validation. Additionally, BaseCookie.js_output() lacked the output validation applied to BaseCookie.output(). | 6.0 | 0.39% | 2026-03-16 | 2026-06-30 |
| CVE-2026-11972 | 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. | 8.2 | 0.43% | 2026-06-23 | 2026-06-30 |
| CVE-2026-11940 | 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 hardlink's shallower path, letting a relative target the filter judged contained escape the destination directory. This allowed a malicious tar archive to create a symlink pointing outside the destination, enabling | 7.8 | 0.60% | 2026-06-23 | 2026-06-30 |
| CVE-2026-6100 | 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 fix cleans up the dangling pointer in this specific error condition. The vulnerability is only present if the program re-uses decompressor instances across multiple decompression calls even after a `MemoryError` is rais | 9.1 | 0.58% | 2026-04-13 | 2026-06-29 |
| CVE-2026-4519 | The webbrowser.open() API would accept leading dashes in the URL which could be handled as command line options for certain web browsers. New behavior rejects leading dashes. Users are recommended to sanitize URLs prior to passing to webbrowser.open(). | 7.0 | 0.31% | 2026-03-20 | 2026-06-29 |
| CVE-2026-9669 | 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 a stack buffer. This could crash the process when processing untrusted data. | 8.2 | 0.38% | 2026-06-08 | 2026-06-23 |
| CVE-2026-7774 | 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 outside the destination directory, subject to the permissions of the extracting process. | 6.9 | 0.61% | 2026-06-04 | 2026-06-17 |
| CVE-2026-7210 | `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 this patch. | 6.3 | 0.81% | 2026-05-11 | 2026-06-17 |
| CVE-2026-4224 | When an Expat parser with a registered ElementDeclHandler parses an inline document type definition containing a deeply nested content model a C stack overflow occurs. | 6.0 | 0.62% | 2026-03-16 | 2026-06-17 |
| CVE-2026-3446 | 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 implementations. Use "validate=True" to enable stricter processing of base64 data. | 6.0 | 0.19% | 2026-04-10 | 2026-06-17 |
| CVE-2026-3298 | 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 affected. | 8.8 | 0.37% | 2026-04-21 | 2026-06-17 |
| CVE-2026-3276 | 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. | 6.3 | 0.47% | 2026-06-03 | 2026-06-17 |
| CVE-2026-3087 | 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. | 6.0 | 0.53% | 2026-04-27 | 2026-06-17 |
| CVE-2026-1299 | The email module, specifically the "BytesGenerator" class, didn’t properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. This is only applicable if using "LiteralHeader" writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in "BytesGenerator". | 6.0 | 0.56% | 2026-01-23 | 2026-06-17 |
| CVE-2026-0672 | When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, and parameters. | 6.0 | 0.40% | 2026-01-20 | 2026-06-17 |
| CVE-2025-8194 | There is a defect in the CPython “tarfile” module affecting the “TarFile” extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability can be mitigated by including the following patch after importing the “tarfile” module: https://gist.github.com/sethmlarson/1716ac5b82b73dbcbf23ad2eff8b33e1 | 7.5 | 0.59% | 2025-07-28 | 2026-06-17 |
| CVE-2025-4517 | Allows arbitrary filesystem writes outside the extraction directory during extraction with filter="data". You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the filter= parameter with a value of "data" or "tar". See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information. Note that for Python 3.14 or later | 9.4 | 1.18% | 2025-06-03 | 2026-06-17 |
| CVE-2025-4435 | 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. | 7.5 | 0.54% | 2025-06-03 | 2026-06-17 |
| CVE-2025-4330 | Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination directory, and the modification of some file metadata. You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the filter= parameter with a value of "data" or "tar". See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for mor | 7.5 | 0.77% | 2025-06-03 | 2026-06-17 |
