RHSA-2026:56357
Vulnerability from csaf_redhat - Published: 2026-08-18 17:02 - Updated: 2026-08-20 20:52A flaw was found in webpack-dev-server. When a user configures a proxy with a broad context, such as '/', and enables WebSocket (ws: true) forwarding, the development server's own Hot Module Replacement (HMR) WebSocket can be intercepted. This interception leads to the leakage of the browser's cookies and Origin header to the proxy target, bypassing the server's Host/Origin validation. Additionally, it can corrupt the HMR socket, resulting in a denial of service for the HMR functionality.

A flaw was found in brace-expansion. A remote attacker can exploit this vulnerability by providing specially crafted input to the expand() function, which can lead to excessive memory consumption. This can cause a denial of service (DoS) by crashing the application due to an out-of-memory error.

A flaw was found in PostCSS, a tool that processes CSS files. An attacker who provides specially crafted CSS input containing a malicious source map comment can cause the system to read arbitrary files from the local filesystem. This can lead to the disclosure of sensitive information, specifically the first few bytes of file content. Additionally, this vulnerability may be exploited to cause a Denial of Service (DoS) by targeting large files, making the system unavailable.

A flaw was found in JavaScript Cookie (js-cookie). This vulnerability allows a remote attacker to manipulate cookie attributes by exploiting a prototype pollution issue within the `assign()` helper function. When processing specially crafted JSON input, the flaw enables an attacker to hijack the prototype of a cookie's attribute object. This allows the attacker to set sensitive cookie attributes such as `domain`, `secure`, `samesite`, `expires`, and `path`, potentially leading to security bypasses or session manipulation.

A flaw was found in the `ip-address` library. This library, used for parsing and manipulating IPv4 and IPv6 addresses in JavaScript, is vulnerable to Server-Side Request Forgery (SSRF) due to incorrect classification of IPv4-mapped/NAT64 IPv6 addresses. An attacker could exploit this misclassification to bypass network restrictions and potentially access or manipulate internal resources. This vulnerability can be exploited on any dual-stack host for IPv4-mapped addresses, and for NAT64, it requires a NAT64/DNS64 gateway in the deployment network.

A flaw was found in the brace-expansion library. The `expand()` function does not apply `maxLength` when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is due to an incomplete mitigation of CVE-2026-14257.

A flaw was found in PostCSS. A remote attacker can exploit this vulnerability by providing a specially crafted sourceMappingURL when a specific configuration (the 'from' parameter) is not set. This can cause the application to read and expose unintended source-map files, potentially revealing sensitive information about the application's source code.

A flaw was found in the `ip-address` library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass security measures like Server-Side Request Forgery (SSRF) filters and potentially gain unauthorized access to internal systems.

A flaw was found in nanoid, a JavaScript library for generating unique string IDs. A remote attacker could exploit an integer overflow vulnerability by providing a specific input to the `nanoid(size)` function. This issue causes the internal random number generator to become predictable, leading to the generation of identical identifiers for session tokens, security tokens (Cross-Site Request Forgery (CSRF) tokens), and API keys. Such predictability could allow an attacker to bypass security measures that rely on unique and random identifiers.

A flaw was found in Browserslist, a tool for sharing browser and Node.js versions. An attacker could provide specially crafted statistics data, which the tool processes without proper validation.

A flaw was found in Browserslist, a configuration tool for front-end development. An attacker can exploit this vulnerability by influencing repeated query values, leading to unbounded memory growth.

By chaining multiple brace groups, an attacker can keep the result count under the limit while making each result progressively longer, causing total memory consumption to grow until the Node.js process crashes with an uncatchable out-of-memory error. This affects any application that passes attacker-influenced strings to brace-expansion directly or transitively via minimatch or glob brace patterns.\n\nNote: In the majority of Red Hat products, brace-expansion is brought in as a transitive dependency of minimatch or glob and is not used at runtime. It is typically only invoked during build or development tooling and is not directly exposed to untrusted network input, reducing the practical exploitability of this flaw.\n\n```\n$ npm ls --omit=dev brace-expansion\nnpm@10.9.8 /usr/lib/node_modules/npm\n`-- minimatch@9.0.9\n `-- brace-expansion@2.0.2\n```",
