Soup Sieve is a CSS selector library designed to be used with Beautiful Soup 4.

axios versions 0.31.1 before 0.33.0 and 1.15.1 before 1.18.0 contain an incomplete depth-limit bypass in toFormData.js when serializing objects with top-level keys ending in '{}'.

lxml is a library for processing XML and HTML in the Python language.

tmp is a temporary file and directory creator for node.js.

axios versions 0.28.0 and later contain uncontrolled recursion in formDataToJSON when processing FormData field names with deeply nested bracket segments.

PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree.

axios versions >=1.15.2 and <1.18.0 contain prototype-pollution read-side gadgets in Basic auth subfield handling (lib/adapters/http.js and lib/helpers/resolveConfig.js).

WebOb provides objects for HTTP requests and responses.

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not.

Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface.

Decoding a maliciously-crafted MIME header containing many invalid encoded-words can consume excessive CPU.

Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322.

Prometheus is an open-source monitoring system and time series database.

Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations.

Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures.

fast-uri accepts a host that contains an unbalanced or misplaced authority bracket without reporting an error.

A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes.

Prometheus is an open-source monitoring system and time series database.

Impact: fast-uri versions from 2.3.1 through 4.1.0 (including the 3.x line up to 3.1.3 and the 2.x line up to 2.4.2) do not treat a literal backslash character (U+005C) as an authority delimiter.

fast-uri serializes the port component of a URI without validating it.

axios in a Node.js deployment using the HTTP adapter can route requests through an attacker-controlled proxy.

nanoid (Nano ID) before 3.3.16 and 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module (nanoid/non-secure).

nanoid (Nano ID) before 5.1.6 contains an infinite loop in the customAlphabet and customRandom functions.

On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /.

A flaw was found in Quay.

A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic.

Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead.

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.
