| 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-2025-6075 | 1 Python | 1 Python | 2026-07-31 | N/A | 5.5 MEDIUM |
| If the value passed to os.path.expandvars() is user-controlled a performance degradation is possible when expanding environment variables. | |||||
| CVE-2026-21441 | 1 Python | 1 Urllib3 | 2026-07-31 | N/A | 7.5 HIGH |
| urllib3 is an HTTP client library for Python. 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. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source. | |||||
| CVE-2026-7210 | 1 Python | 1 Python | 2026-07-27 | N/A | 7.5 HIGH |
| `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. | |||||
| CVE-2026-6019 | 1 Python | 1 Python | 2026-07-27 | N/A | 6.1 MEDIUM |
| http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes " for JavaScript string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value. | |||||
| 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-2026-42308 | 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-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-2026-44432 | 1 Python | 1 Urllib3 | 2026-07-24 | 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-2026-4360 | 1 Python | 1 Python | 2026-07-23 | N/A | 5.3 MEDIUM |
| In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks. An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract() function. | |||||
| CVE-2026-15308 | 1 Python | 1 Python | 2026-07-23 | N/A | 7.5 HIGH |
| The incremental HTML parser (html.parser.HTMLParser) allows for CPU denial-of-service through repeated unterminated markup declarations when processing uncontrolled data. | |||||
| CVE-2026-59204 | 1 Python | 1 Pillow | 2026-07-21 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates total_component_width across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and trigger out-of-memory failures during decoding. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-59197 | 1 Python | 1 Pillow | 2026-07-21 | N/A | 8.2 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size because ImageFilter.RankFilter.filter() calls image.expand(size // 2, size // 2) before rank-filter size validation and ImagingExpand() computes output dimensions with unchecked signed int arithmetic. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-59200 | 1 Python | 1 Pillow | 2026-07-21 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode() in PIL/PdfParser.py calls zlib.decompress() with bufsize set to the PDF stream Length field without bounding the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small file. This issue is fixed in version 12.3.0. | |||||
| CVE-2026-25990 | 1 Python | 1 Pillow | 2026-07-21 | 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-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-2026-40192 | 1 Python | 1 Pillow | 2026-07-20 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Versions 10.3.0 through 12.1.1 did not limit the amount of GZIP-compressed data read when decoding a FITS image, making them vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe performance degradation). If users are unable to immediately upgrade, they should only open specific image formats, excluding FITS, as a workaround. | |||||
| CVE-2026-59199 | 1 Python | 1 Pillow | 2026-07-15 | N/A | 7.5 HIGH |
| Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste(), Image.crop(), or Image.alpha_composite(). This issue is fixed in version 12.3.0. | |||||
| 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. | |||||
