| CVE-2025-13836 | 1 Python | 1 Python | 2026-09-03 | N/A | 7.5 HIGH |
| When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS. | |||||
| CVE-2026-4519 | 1 Python | 1 Python | 2026-08-13 | N/A | 3.3 LOW |
| 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(). | |||||
| CVE-2026-4224 | 1 Python | 1 Python | 2026-08-13 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2026-3644 | 1 Python | 1 Python | 2026-08-13 | N/A | 7.5 HIGH |
| 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(). | |||||
| CVE-2025-13462 | 1 Python | 1 Python | 2026-08-13 | N/A | 3.3 LOW |
| The "tarfile" module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations. | |||||
| CVE-2023-6507 | 1 Python | 1 Python | 2026-07-31 | N/A | 6.1 MEDIUM |
| An issue was found in CPython 3.12.0 `subprocess` module on POSIX platforms. The issue was fixed in CPython 3.12.1 and does not affect other stable releases. When using the `extra_groups=` parameter with an empty list as a value (ie `extra_groups=[]`) the logic regressed to not call `setgroups(0, NULL)` before calling `exec()`, thus not dropping the original processes' groups before starting the new process. There is no issue when the parameter isn't used or when any value is used besides an empty list. This issue only impacts CPython processes run with sufficient privilege to make the `setgroups` system call (typically `root`). | |||||
| CVE-2009-3720 | 3 Apache, Libexpat Project, Python | 4 Http Server, Libexpat, Python and 1 more | 2026-07-20 | 5.0 MEDIUM | N/A |
| The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625. | |||||
| CVE-2025-12781 | 1 Python | 1 Python | 2026-06-17 | N/A | 5.3 MEDIUM |
| When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. This behavior matches what is recommended in earlier base64 RFCs, but newer RFCs now recommend either dropping characters outside the specified base64 alphabet or raising an error. The old behavior has the possibility of causing data integrity issues. This behavior can only be insecure if your application uses an alternate base64 alphabet (without "+/"). If your application does not use the "altchars" parameter or the urlsafe_b64decode() function, then your application does not use an alternative base64 alphabet. The attached patches DOES NOT make the base64-decode behavior raise an error, as this would be a change in behavior and break existing programs. Instead, the patch deprecates the behavior which will be replaced with the newly recommended behavior in a future version of Python. Users are recommended to mitigate by verifying user-controlled inputs match the base64 alphabet they are expecting or verify that their application would not be affected if the b64decode() functions accepted "+" or "/" outside of altchars. | |||||
| CVE-2025-12084 | 1 Python | 1 Python | 2026-06-17 | N/A | 5.3 MEDIUM |
| When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively nested documents. | |||||
| CVE-2024-7592 | 1 Python | 1 Python | 2026-06-17 | N/A | 7.5 HIGH |
| There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value. | |||||
| CVE-2024-6232 | 1 Python | 1 Python | 2026-06-17 | N/A | 7.5 HIGH |
| There is a MEDIUM severity vulnerability affecting CPython. Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives. | |||||
| CVE-2023-41105 | 2 Netapp, Python | 2 Active Iq Unified Manager, Python | 2026-06-17 | N/A | 7.5 HIGH |
| An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible cases in which an application would have rejected a filename for security reasons in Python 3.10.x or earlier, but that filename is no longer rejected in Python 3.11.x. | |||||
| CVE-2023-40217 | 1 Python | 1 Python | 2026-06-17 | N/A | 5.3 MEDIUM |
| An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly, there is a brief window where the SSLSocket instance will detect the socket as "not connected" and won't initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication, and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path requires that the connection be closed on initialization of the SSLSocket.) | |||||
| CVE-2023-38898 | 1 Python | 1 Python | 2026-06-17 | N/A | 5.3 MEDIUM |
| An issue in Python cpython v.3.7 allows an attacker to obtain sensitive information via the _asyncio._swap_current_task component. NOTE: this is disputed by the vendor because (1) neither 3.7 nor any other release is affected (it is a bug in some 3.12 pre-releases); (2) there are no common scenarios in which an adversary can call _asyncio._swap_current_task but does not already have the ability to call arbitrary functions; and (3) there are no common scenarios in which sensitive information, which is not already accessible to an adversary, becomes accessible through this bug. | |||||
| CVE-2023-36632 | 1 Python | 1 Python | 2026-06-17 | N/A | 7.5 HIGH |
| The legacy email.utils.parseaddr function in Python through 3.11.4 allows attackers to trigger "RecursionError: maximum recursion depth exceeded while calling a Python object" via a crafted argument. This argument is plausibly an untrusted value from an application's input data that was supposed to contain a name and an e-mail address. NOTE: email.utils.parseaddr is categorized as a Legacy API in the documentation of the Python email package. Applications should instead use the email.parser.BytesParser or email.parser.Parser class. NOTE: the vendor's perspective is that this is neither a vulnerability nor a bug. The email package is intended to have size limits and to throw an exception when limits are exceeded; they were exceeded by the example demonstration code. | |||||
| CVE-2023-33595 | 1 Python | 1 Python | 2026-06-17 | N/A | 5.5 MEDIUM |
| CPython v3.12.0 alpha 7 was discovered to contain a heap use-after-free via the function ascii_decode at /Objects/unicodeobject.c. | |||||
| CVE-2023-27043 | 3 Fedoraproject, Netapp, Python | 4 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 1 more | 2026-06-17 | N/A | 5.3 MEDIUM |
| The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python. | |||||
| CVE-2022-48566 | 3 Debian, Netapp, Python | 4 Debian Linux, Active Iq Unified Manager, Converged Systems Advisor Agent and 1 more | 2026-06-17 | N/A | 5.9 MEDIUM |
| An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimisations were possible in the accumulator variable in hmac.compare_digest. | |||||
| CVE-2022-48565 | 2 Debian, Python | 2 Debian Linux, Python | 2026-06-17 | N/A | 9.8 CRITICAL |
| An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. | |||||
| CVE-2022-48564 | 2 Netapp, Python | 2 Active Iq Unified Manager, Python | 2026-06-17 | N/A | 6.5 MEDIUM |
| read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. | |||||
