RHSA-2026:8483
Vulnerability from csaf_redhat - Published: 2026-04-16 13:44 - Updated: 2026-04-16 20:43A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.
A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not correctly handle hostname normalization when evaluating NO_PROXY rules. An attacker can exploit this by crafting requests to loopback addresses (e.g., localhost. or [::1]) which bypass the NO_PROXY configuration and are routed through the configured proxy. This can lead to Server-Side Request Forgery (SSRF) vulnerabilities, enabling attackers to access sensitive internal or loopback services that should otherwise be protected.
A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security (TLS) session resumption when certificate authority (CA) settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing a client or server to establish a connection that should have been rejected. This could lead to an authentication bypass under specific conditions.
A flaw was found in lodash. The fix for CVE-2021-23337 added validation for the variable option in _.template but did not apply the same validation to options.imports key names. Both paths flow into the same Function() constructor sink. Additionally, _.template uses assignInWith to merge imports, which enumerates inherited properties via for..in. If Object.prototype has been polluted by any other vector, the polluted keys are copied into the imports object and passed to Function().
The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid.
A flaw was found in Rollup, a JavaScript module bundler. Insecure file name sanitization in the core engine allows an attacker to control output filenames, potentially through command-line interface (CLI) inputs, manual chunk aliases, or malicious plugins. By using directory traversal sequences (`../`), an attacker can overwrite files anywhere on the host filesystem where the build process has write permissions. This vulnerability can lead to persistent remote code execution (RCE) by overwriting critical system or user configuration files.
A flaw was found in Immutable.js, a library for persistent immutable data structures. This vulnerability, known as Prototype Pollution, allows an attacker with low privileges to inject unwanted properties into core JavaScript object prototypes without user interaction. By manipulating specific APIs such as mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject(), a remote attacker could potentially execute arbitrary code or cause a denial of service (DoS).
A flaw was found in SVGO, an SVG (Scalable Vector Graphics) Optimizer. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by submitting a specially crafted XML file. The application's failure to properly guard against XML entity expansion or recursion can lead to the Node.js process consuming excessive memory and crashing.
A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 `:path` pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed `:path` that omits the mandatory leading slash. This allows the attacker to bypass defined security policies, potentially leading to unauthorized access to services or information disclosure.
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, known as Prototype Pollution, can be exploited through a specific "Gadget" attack chain. This allows an attacker to escalate a Prototype Pollution vulnerability in a third-party dependency, potentially leading to remote code execution or a full cloud compromise, such as bypassing AWS IMDSv2.
