| CVE-2026-59203 | 1 Python | 1 Pillow | 2026-07-15 | N/A | 5.3 MEDIUM |
| Pillow is a Python imaging library. From 12.0.0 through 12.2.0, Pillow's EPS parser in PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive, allowing a crafted EPS file to cause Image.open() to seek backwards to the same directive and parse it repeatedly in an infinite loop. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-4519 | 1 Python | 1 Python | 2026-07-15 | 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-2026-59198 | 1 Python | 1 Pillow | 2026-07-14 | N/A | 6.5 MEDIUM |
| Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-59205 | 1 Python | 1 Pillow | 2026-07-14 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.apply(im, imOut) API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. This issue is fixed in version 12.3.0. | |||||
| CVE-2018-25032 | 12 Apple, Azul, Debian and 9 more | 39 Mac Os X, Macos, Zulu and 36 more | 2026-07-14 | 5.0 MEDIUM | 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-2026-59890 | 1 Python | 1 Setuptools | 2026-07-13 | N/A | 6.1 MEDIUM |
| setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0. | |||||
| CVE-2026-55379 | 1 Python | 1 Pillow | 2026-07-07 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdf_char() read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new() without calling Image._decompression_bomb_check(), bypassing Pillow's documented decompression bomb protection and allowing excessive memory allocation. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-55380 | 1 Python | 1 Pillow | 2026-07-07 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile._open() read image dimensions from the GD 2.x header and stored them in self._size without calling Image._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-54060 | 1 Python | 1 Pillow | 2026-07-07 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-glyph images into a combined bitmap with Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), allowing a font to trigger excessive allocation during conversion or saving. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-55798 | 1 Python | 1 Pillow | 2026-07-07 | N/A | 4.5 MEDIUM |
| Pillow is a Python imaging library. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe shell command by directly embedding a file path into an f-string without escaping and passed the result to subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary cmd.exe commands. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-54059 | 1 Python | 1 Pillow | 2026-07-07 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py _load_bitmaps() read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes() without calling Image._decompression_bomb_check(), allowing crafted PCF font data to cause excessive memory allocation. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-3644 | 1 Python | 1 Python | 2026-06-30 | 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-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-2026-5271 | 1 Python | 1 Pymanager | 2026-06-17 | N/A | 7.8 HIGH |
| pymanager included the current working directory in sys.path meaning modules could be shadowed by modules in the current working directory. As a result, if a user executes a pymanager-generated command (e.g., pip, pytest) from an attacker-controlled directory, a malicious module in that directory can be imported and executed instead of the intended package. | |||||
| CVE-2026-4224 | 1 Python | 1 Python | 2026-06-17 | 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-2026-3087 | 2 Microsoft, Python | 2 Windows, Python | 2026-06-17 | N/A | 7.5 HIGH |
| 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-2026-31900 | 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-2025-66471 | 1 Python | 1 Urllib3 | 2026-06-17 | N/A | 7.5 HIGH |
| urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data. | |||||
| CVE-2025-66418 | 1 Python | 1 Urllib3 | 2026-06-17 | N/A | 7.5 HIGH |
| urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation for the decompressed data. This vulnerability is fixed in 2.6.0. | |||||
