CVE Vulnerability Catalog

Git defines a line-based protocol used to exchange information between Git and Git credential helpers. Some ecosystems (most likely those using this protocol) may be vulnerable to attacks related to this protocol.

An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.

Repeated use of the Unpacker after an error occurs may cause the process to crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack.

A heap buffer overflow vulnerability was discovered in Perl. Affected versions include release branches 5.34, 5.36, 5.38, and 5.40, as well as development versions from 5.33.1 through 5.41.10. When non-ASCII bytes are present in the left-hand side of the `tr` operator, `S_do_trans_invmap` can overflow the buffer.

GitPython spent 2022-2026 rolling out two reusable guards method-by-method: Git.check_unsafe_protocols(url) (raises UnsafeProtocolError for <transport>:: remote-helper URLs) and Git.check_unsafe_options(...) (raises UnsafeOptionError for denylisted options). The description indicates the rollout did not cover all code paths.

A call to the token endpoint with a grant type of urn:ietf:params:oauth:grant-type:device_code and a bogus device_code can obtain a bearer token as long as a valid client ID enabled for the device workflow is known. This violates RFC 8628.

Multiple cases were found in aiohttp where excessive or unbounded memory use, or excessive CPU consumption, can be triggered by attacker-controlled requests. An attacker could cause resource exhaustion through specially crafted requests.

Pillow wheels from 11.1.0 onward bundle a libopenjp2 containing a heap-buffer-overflow write that is fixed upstream on master but has never appeared in an OpenJPEG release. Because the wheel bundles its own copy, a patched host library does not protect against the issue.

The description of this report does not contain sufficient technical information about the vulnerability — it only includes a note about the reporting method and references to files that were not attached. The nature and scope of the issue cannot be determined from it.

In Pillow's libtiff encoder (PyImaging_LibTiffEncoderNew in src/encode.c), crafted TIFF tags can cause memory disclosure and a segfault. The issue occurs when creating the LibTiff encoder.

In GitPython, Remote.pull() forwards its positional refspec argument directly to the git pull child process while its unsafe-option guard inspects only keyword arguments. An application that passes attacker-influenced data as the refspec (e.g., a user-supplied branch name) may allow injection of unsafe options.

GitPython's config-name validator only neutralizes CR/LF/NUL for the "option" label; it does not reject =, #, ;, [, ], or whitespace in an option name. write_section writes the option name verbatim into the config file, so an option name such as sshCommand = touch <cmd> can inject configuration.

This is a residual of GHSA-g5vv-9gxw-82hx / CVE-2026-87819. The 3.1.60 fix made Actor._from_string regex-free, but parse_actor_and_date still runs _re_actor_epoch on the same author/committer/tagger line one step earlier. That pattern backtracks quadratically when the trailing epo...

A vulnerability in the Crass library involves unbounded exponentiation when converting CSS scientific notation number values before clamping the result to Float::MAX. Applications that use Crass to parse attacker-controlled CSS strings can be forced to consume excessive CPU and memory when processing a tiny input.

The faraday-http-cache library stores cached responses in JSON format by default and reads them back using JSON.load, which honors the json_class key and calls json_create on the named class. Response headers are stored verbatim in the cache entry, so a malicious origin server can return a response with a json_class key leading to unsafe deserialization.

A memory-related vulnerability has been discovered and fixed in the librsvg dependency. Under certain runtime-specific conditions, it can lead to possible remote code execution (RCE) on glibc-based Linux.

The filepath package in Go does not recognize paths with a \??\ prefix as special. On Windows, a path starting with \??\ is equivalent to a path starting with \\?\ and can be used to access arbitrary system locations.

Vulnerability in CPAN 2.28 allows signature verification bypass. An attacker can supply unauthorized code that is treated as properly signed.

The pip package before version 19.2 for Python is vulnerable to directory traversal when a URL is provided in an install command. An attacker can exploit a Content-Disposition header containing '../' in the filename to overwrite files, such as /root/.ssh/authorized_keys.

CPAN.pm before version 2.35 does not verify TLS certificates when downloading distributions over HTTPS. This allows man-in-the-middle attackers to replace downloaded packages with malicious ones.
