| CVE-2026-44432 | 1 Python | 1 Urllib3 | 2026-09-10 | N/A | 7.5 HIGH |
| urllib3 is an HTTP client library for Python. From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion (1) during the second HTTPResponse.read(amt=N) call when the response was decompressed using the official Brotli library or (2) when HTTPResponse.drain_conn() was called after the response had been read and decompressed partially (compression algorithm did not matter here). These issues could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This could result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data) on the client side. This vulnerability is fixed in 2.7.0. | |||||
| CVE-2026-25990 | 1 Python | 1 Pillow | 2026-09-10 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. From 10.3.0 to before 12.1.1, an out-of-bounds write may be triggered when loading a specially crafted PSD image. This vulnerability is fixed in 12.1.1. | |||||
| CVE-2025-13837 | 1 Python | 1 Python | 2026-09-03 | N/A | 5.5 MEDIUM |
| When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues | |||||
| 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-2026-32274 | 1 Python | 1 Black | 2026-08-03 | N/A | 7.5 HIGH |
| Black is the uncompromising Python code formatter. Starting in version 24.3.0 and prior to version 26.3.1, Black writes a cache file, the name of which is computed from various formatting options. The value of the --python-cell-magics option was placed in the filename without sanitization, which allowed an attacker who controls the value of this argument to write cache files to arbitrary file system locations. Fixed in Black 26.3.1. | |||||
| 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-2026-42311 | 1 Python | 1 Pillow | 2026-07-24 | N/A | 7.8 HIGH |
| Pillow is a Python imaging library. From version 10.3.0 to before version 12.2.0, processing a malicious PSD file could lead to memory corruption, potentially resulting in a crash or arbitrary code execution. This issue has been patched in version 12.2.0. | |||||
| CVE-2026-42310 | 1 Python | 1 Pillow | 2026-07-24 | N/A | 5.5 MEDIUM |
| Pillow is a Python imaging library. From version 4.2.0 to before version 12.2.0, an attacker can supply a malicious PDF that causes the process to hang indefinitely, consuming 100% CPU and making the application unresponsive. This issue has been patched in version 12.2.0. | |||||
| CVE-2026-42308 | 1 Python | 1 Pillow | 2026-07-24 | N/A | 5.5 MEDIUM |
| Pillow is a Python imaging library. Prior to version 12.2.0, if a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This issue has been patched in version 12.2.0. | |||||
| CVE-2026-42309 | 1 Python | 1 Pillow | 2026-07-24 | N/A | 5.5 MEDIUM |
| Pillow is a Python imaging library. From version 11.2.1 to before version 12.2.0, passing nested lists as coordinates to APIs that accept coordinates such as ImagePath.Path, ImageDraw.ImageDraw.polygon and ImageDraw.ImageDraw.line could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists are now validated to contain exactly two numeric coordinates. This issue has been patched in version 12.2.0. | |||||
| 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-2026-44431 | 1 Python | 1 Urllib3 | 2026-06-26 | N/A | 5.3 MEDIUM |
| urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still forward these sensitive headers. This vulnerability is fixed in 2.7.0. | |||||
| CVE-2026-31900 | 1 Python | 1 Black | 2026-06-17 | N/A | 9.8 CRITICAL |
| Black is the uncompromising Python code formatter. Black provides a GitHub action for formatting code. This action supports an option, use_pyproject: true, for reading the version of Black to use from the repository pyproject.toml. A malicious pull request could edit pyproject.toml to use a direct URL reference to a malicious repository. This could lead to arbitrary code execution in the context of the GitHub Action. Attackers could then gain access to secrets or permissions available in the context of the action. Version 26.3.0 fixes this vulnerability. | |||||
| CVE-2026-25645 | 1 Python | 1 Requests | 2026-06-17 | N/A | 4.4 MEDIUM |
| Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access. | |||||
| CVE-2025-50182 | 1 Python | 1 Urllib3 | 2026-06-17 | N/A | 5.3 MEDIUM |
| urllib3 is a user-friendly HTTP client library for Python. Starting in version 2.2.0 and prior to 2.5.0, urllib3 does not control redirects in browsers and Node.js. urllib3 supports being used in a Pyodide runtime utilizing the JavaScript Fetch API or falling back on XMLHttpRequest. This means Python libraries can be used to make HTTP requests from a browser or Node.js. Additionally, urllib3 provides a mechanism to control redirects, but the retries and redirect parameters are ignored with Pyodide; the runtime itself determines redirect behavior. This issue has been patched in version 2.5.0. | |||||
| CVE-2025-50181 | 1 Python | 1 Urllib3 | 2026-06-17 | N/A | 5.3 MEDIUM |
| urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable redirects. By default, requests and botocore users are not affected. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0. | |||||
