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.
7.0 (High)

https://access.redhat.com/errata/RHSA-2026:9742
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in Python-Markdown. Parsing crafted markdown content containing malformed HTML-like sequences causes html.parser.HTMLParser to raise an unhandled AssertionError. This unhandled exception allows an attacker to cause an application crash and potentially disclose sensitive information via its stack trace.
8.2 (High)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this vulnerability, wrap your markdown parsing function in a try/except block. This catches the unhandled exception, preventing both the application crash and the stack trace leak.
A flaw was found in ajv. When the $data option is enabled, the value of the pattern keyword is passed directly to the JavaScript RegExp() constructor without sufficient validation. An attacker able to supply a malicious regular expression pattern can trigger a ReDoS (Regular Expression Denial of Service), causing the application to become unresponsive and resulting in a denial of service.
7.5 (High)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this issue, disable the $data feature if your application does not require it. If $data must be used, implement strict validation of the input fields that are referenced by the pattern keyword to ensure they contain only expected and safe characters.
A flaw was found in undici, a Node.js HTTP/1.1 client. A remote attacker could exploit this vulnerability by sending HTTP/1.1 requests that include duplicate Content-Length headers with different casing (e.g., "Content-Length" and "content-length"). This can lead to HTTP Request Smuggling, a technique where an attacker sends an ambiguous request that is interpreted differently by a proxy and a backend server. Successful exploitation could result in unauthorized access, cache poisoning, or credential hijacking. It may also cause a Denial of Service (DoS) if strict HTTP parsers reject the malformed requests.
7.3 (High)
Vendor Fix

Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in undici. A remote attacker can exploit this vulnerability by sending a specially crafted compressed frame, known as a "decompression bomb," during permessage-deflate decompression. The undici WebSocket client does not properly limit the size of decompressed data, leading to unbounded memory consumption. This can cause the Node.js process to exhaust available memory, resulting in a denial of service (DoS) where the process crashes or becomes unresponsive.
7.5 (High)
Vendor Fix

Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in undici. A remote attacker could exploit this vulnerability by sending a specially crafted WebSocket frame with an extremely large 64-bit length. This causes undici's ByteParser to overflow its internal calculations, leading to an invalid state and a fatal TypeError. The primary consequence is a Denial of Service (DoS), which terminates the process.

Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in the undici WebSocket client. A remote malicious server can exploit this vulnerability by sending a WebSocket frame with an invalid `server_max_window_bits` parameter within the permessage-deflate extension. This improper validation causes the client's Node.js process to terminate, leading to a denial-of-service (DoS) condition for the client.

Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A security flaw was identified in the Orchestrator Plugin of Red Hat Developer Hub (Backstage). The issue occurs due to insufficient input validation in GraphQL query handling. An authenticated user can inject specially crafted input into API requests, which disrupts backend query processing. This results in the entire Backstage application crashing and restarting, leading to a platform-wide Denial of Service (DoS). As a result, legitimate users temporarily lose access to the platform.
6.5 (Medium)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this issue, restrict network access to the Red Hat Developer Hub instance to trusted users and networks only. This limits the exposure of the vulnerable Orchestrator Plugin to unauthorized access.
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().

Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in path-to-regexp. A remote attacker could exploit this vulnerability by providing specially crafted input that generates a regular expression with multiple sequential optional groups. This leads to an exponential growth in the generated regular expression, causing a Denial of Service (DoS) due to excessive resource consumption.
7.5 (High)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this vulnerability, limit the use of multiple sequential optional groups in route patterns within applications that use `path-to-regexp`. Additionally, avoid directly passing user-controlled input as route patterns to prevent the generation of maliciously crafted regular expressions.
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.
7.5 (High)
Vendor Fix

https://access.redhat.com/errata/RHSA-2026:9742
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in minimatch. A remote attacker could exploit this Regular Expression Denial of Service (ReDoS) vulnerability by providing a specially crafted glob pattern. This pattern, containing numerous consecutive wildcard characters, causes excessive processing and exponential backtracking in the regular expression engine. Successful exploitation leads to a Denial of Service (DoS), making the application unresponsive.

A flaw was found in Underscore.js, a JavaScript utility library. This vulnerability allows a remote attacker to trigger a Denial of Service (DoS) attack by providing specially crafted recursive data structures. When these structures are processed by the _.flatten or _.isEqual functions, which lack a depth limit for recursion, a stack overflow occurs. This can make the application unavailable to legitimate users.
5.9 (Medium)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this issue, applications utilizing Underscore.js should ensure that any processing of untrusted, recursively structured data with `_.flatten` or `_.isEqual` explicitly enforces a finite depth limit. Review application code to identify and modify calls to these functions, adding appropriate depth parameters to prevent stack overflow conditions. Additionally, input validation should be implemented to sanitize untrusted data before it is processed by Underscore.js functions.
A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and resulting in a Denial of Service (DoS).
6.5 (Medium)
Vendor Fix

https://access.redhat.com/errata/RHSA-2026:9742
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in Backstage. The backstage/plugin-techdocs-node package uses an allowlist to filter dangerous MkDocs configuration keys during the documentation build process. A gap in this allowlist allows attackers to craft an mkdocs.yml file that causes arbitrary Python code execution.
9.1 (Critical)
Vendor Fix
For more about Red Hat Developer Hub, see References links
https://access.redhat.com/errata/RHSA-2026:9742
Workaround
To mitigate this issue, enable docker isolation by updating the Backstage configuration to use 'runIn: docker' instead of 'runIn: local', confining the arbitrary Python code execution to a containerized environment. Additionally, limit commit access to repositories tracked by Backstage to trusted contributors only, and enforce mandatory pull request (PR) reviews for any modifications made to the mkdocs.yml file.
A denial of service flaw has been discovered in the flatted npm library. flatted's parse() function uses a recursive revive() phase to resolve circular references in deserialized JSON. When given a crafted payload with deeply nested or self-referential $ indices, the recursion depth is unbounded, causing a stack overflow that crashes the Node.js process.
7.5 (High)
Vendor Fix

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in Forge (also known as node-forge), a JavaScript implementation of Transport Layer Security (TLS). The `pki.verifyCertificateChain()` function does not properly enforce certificate validation rules. This oversight allows an intermediate certificate that lacks specific security extensions to enable any leaf certificate to function as a Certificate Authority (CA) and sign other certificates. Consequently, node-forge could accept these unauthorized certificates as valid, potentially leading to spoofing or the issuance of illegitimate certificates.

This can lead to Server-Side Request Forgery (SSRF) vulnerabilities, enabling attackers to access sensitive internal or loopback services that should otherwise be protected.",
