CVE-2026-6321

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator (URL) containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization, leading to distinct URLs resolving to the same internal path. This could allow an attacker to bypass security policies that rely on path-based comparisons, potentially gaining unauthorized access to resources.

CVE-2026-32280

A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.

CVE-2026-32281

A flaw was found in Go's `crypto/x509` package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service (DoS) for applications or systems performing certificate validation.

CVE-2026-32282

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the `Root.Chmod` function is replaced with a symbolic link during execution, specifically after `Root.Chmod` checks the target but before acting, the `chmod` operation will be performed on the file the symbolic link points to. This issue can bypass directory restrictions and lead to unauthorized permission changes on the filesystem.

CVE-2026-40895

A flaw was found in follow-redirects. When an HTTP request follows a cross-domain redirect (a redirection to a different domain), custom authentication headers, such as X-API-Key or X-Auth-Token, are not properly stripped. This allows these sensitive headers to be forwarded verbatim to the redirect target, potentially leading to the unintended disclosure of authentication information to an untrusted third party.

CVE-2026-41240

A flaw was found in DOMPurify, a DOM-only cross-site scripting sanitizer. A remote attacker could exploit an inconsistency in how forbidden tags and attributes are handled when function-based tag additions are used. This allows malicious HTML, MathML, or SVG elements to bypass sanitization and execute arbitrary code in the user's browser, leading to Cross-Site Scripting (XSS).

CVE-2026-41242

A flaw was found in protobufjs, a JavaScript (JS) library used for compiling protobuf definitions. A remote attacker with low privileges can exploit this vulnerability by injecting arbitrary code into the "type" fields of protobuf definitions. This malicious code will then execute during the object decoding process, leading to arbitrary code execution and potentially full system compromise.

CVE-2026-41674

A flaw was found in xmldom and @xmldom/xmldom, a JavaScript library for parsing and serializing XML. This vulnerability allows an attacker to inject arbitrary XML markup into a document due to improper handling of DocumentType node fields during serialization. By crafting malicious input, an attacker can cause the XML serializer to prematurely terminate the DOCTYPE declaration, enabling the insertion of unauthorized content. This could lead to information disclosure or, in certain configurations, the execution of arbitrary code.

CVE-2026-42033

A flaw was found in Axios, an HTTP client library. This vulnerability allows an attacker to exploit a prototype pollution issue if another part of the application has already polluted the Object.prototype. By doing so, the attacker can intercept and modify JSON responses or take control of the HTTP communication. This could lead to unauthorized access to sensitive information like user credentials and request details.

CVE-2026-42035

A flaw was found in Axios, a software library for making network requests. A remote attacker can exploit a prototype pollution vulnerability to inject arbitrary HTTP headers into outgoing requests. This occurs when the application's core object definitions are manipulated, causing Axios to misinterpret data and include attacker-controlled headers in network communications. This could lead to unauthorized actions or data manipulation.

CVE-2026-42039

A flaw was found in Axios, a promise-based HTTP client for browsers and Node.js. This vulnerability occurs because the `toFormData` function recursively processes nested objects without a depth limit. A remote attacker can exploit this by sending deeply nested request data, which causes the Node.js process to crash due to a RangeError, leading to a potential Denial of Service (DoS) if the process crashes.

Threats
Impact Important
CVE-2026-42041

A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the `Object.prototype.validateStatus` property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.

8.2 (High)

Threats
Impact Important
CVE-2026-42043

A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses (within the 127.0.0.0/8 range, excluding 127.0.0.1), the attacker can completely bypass the NO_PROXY protection, potentially leading to unauthorized access or information disclosure within the network. This issue is an incomplete fix for a previous vulnerability.

CVE-2026-42044

A flaw was found in Axios, a widely used HTTP client. This vulnerability, known as a Prototype Pollution "Gadget" attack, allows a remote attacker to subtly alter JSON API responses. By manipulating a specific function, an attacker can selectively modify data within these responses. This could lead to significant security breaches, including unauthorized privilege escalation, fraudulent balance manipulation, or bypassing critical authorization checks.

A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator (URL) containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization, leading to distinct URLs resolving to the same internal path. This could allow an attacker to bypass security policies that rely on path-based comparisons, potentially gaining unauthorized access to resources.",
