| CVE-2021-28861 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Python, Enterprise Linux and 1 more | 2025-12-18 | 6.5 Medium |
| Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks." | ||||
| CVE-2021-23336 | 7 Debian, Djangoproject, Fedoraproject and 4 more | 14 Debian Linux, Django, Fedora and 11 more | 2025-12-18 | 5.9 Medium |
| The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter. | ||||
| CVE-2022-0391 | 5 Fedoraproject, Netapp, Oracle and 2 more | 12 Fedora, Active Iq Unified Manager, Hci and 9 more | 2025-12-18 | 7.5 High |
| A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14. | ||||
| CVE-2013-0340 | 3 Apple, Libexpat Project, Python | 7 Ipados, Iphone Os, Macos and 4 more | 2025-11-25 | N/A |
| expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. | ||||
| CVE-2024-9287 | 2 Python, Redhat | 4 Cpython, Python, Enterprise Linux and 1 more | 2025-11-04 | 7.8 High |
| A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/bin/activate"). This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected. | ||||
| CVE-2024-7592 | 2 Python, Redhat | 3 Cpython, Python, Enterprise Linux | 2025-11-04 | 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 | 2 Python, Redhat | 8 Cpython, Python, Enterprise Linux and 5 more | 2025-11-04 | 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-2023-40217 | 2 Python, Redhat | 8 Python, Enterprise Linux, Rhel Aus and 5 more | 2025-11-04 | 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-2023-24329 | 4 Fedoraproject, Netapp, Python and 1 more | 14 Fedora, Active Iq Unified Manager, Management Services For Element Software and 11 more | 2025-11-04 | 7.5 High |
| An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters. | ||||
| CVE-2022-45061 | 4 Fedoraproject, Netapp, Python and 1 more | 13 Fedora, Active Iq Unified Manager, Bootstrap Os and 10 more | 2025-11-04 | 7.5 High |
| An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. | ||||
| CVE-2022-42919 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Python, Enterprise Linux and 1 more | 2025-11-04 | 7.8 High |
| Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do that in CPython before 3.9. | ||||
| CVE-2021-3733 | 4 Fedoraproject, Netapp, Python and 1 more | 21 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 18 more | 2025-11-04 | 6.5 Medium |
| There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. | ||||
| CVE-2021-29921 | 3 Oracle, Python, Redhat | 8 Communications Cloud Native Core Automated Test Suite, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Slice Selection Function and 5 more | 2025-11-04 | 9.8 Critical |
| In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses. | ||||
| CVE-2020-10735 | 3 Fedoraproject, Python, Redhat | 7 Fedora, Python, Enterprise Linux and 4 more | 2025-11-04 | 7.5 High |
| A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int("text"), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability. | ||||
| CVE-2015-20107 | 4 Fedoraproject, Netapp, Python and 1 more | 7 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 4 more | 2025-11-04 | 7.6 High |
| In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 | ||||
| CVE-2018-25032 | 13 Apple, Azul, Debian and 10 more | 47 Mac Os X, Macos, Zulu and 44 more | 2025-08-21 | 7.5 High |
| zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. | ||||
| CVE-2019-12900 | 7 Bzip, Canonical, Debian and 4 more | 9 Bzip2, Ubuntu Linux, Debian Linux and 6 more | 2025-06-09 | 9.8 Critical |
| BZ2_decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors. | ||||
| CVE-2016-3189 | 2 Bzip, Python | 2 Bzip2, Python | 2025-06-09 | 6.5 Medium |
| Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start of the block. | ||||
| CVE-2019-15903 | 3 Libexpat Project, Python, Redhat | 5 Libexpat, Python, Enterprise Linux and 2 more | 2025-05-30 | 6.5 Medium |
| In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. | ||||
| CVE-2022-37454 | 9 Debian, Extended Keccak Code Package Project, Fedoraproject and 6 more | 9 Debian Linux, Extended Keccak Code Package, Fedora and 6 more | 2025-05-08 | 9.8 Critical |
| The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface. | ||||
