CVE-2026-25896

A flaw was found in fast-xml-parser. A remote attacker can exploit this vulnerability by providing a specially crafted XML input. The system incorrectly interprets a dot in a DOCTYPE entity name as a regular expression wildcard during processing. This allows the attacker to bypass security measures and inject malicious scripts, resulting in Cross-Site Scripting (XSS) when the parsed output is displayed to users.

A denial of service flaw was found in fast-xml-parser. A remote attacker can exploit this vulnerability by providing a specially crafted, small XML input. This input can force the XML parser to perform an unlimited amount of entity expansion, consuming excessive resources. This can lead to the application freezing for an extended period, resulting in a Denial of Service (DoS).

CVE-2026-27606

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.

CVE-2026-33186

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.

In Red Hat\u2013shipped configurations, this option is not enabled by default, and the vulnerable code path is therefore not exercised under typical deployments.\nThe underlying issue results in uncontrolled recursion leading to a stack overflow condition, which causes the application to terminate unexpectedly. While this can be triggered via crafted input, the impact is limited strictly to denial of service (DoS) and does not provide a mechanism for arbitrary code execution, privilege escalation, or data disclosure.\nFurthermore, exploitation requires that the affected application processes attacker-controlled XML input through the XML builder functionality with the specific vulnerable configuration enabled. This significantly reduces the attack surface and introduces environmental constraints not considered in the generalized NVD scoring.\n\nGiven the absence of confidentiality and integrity impact, the requirement for non-default configuration, and the limitation of the impact to process termination, Red Hat considers the practical risk to be lower than the NVD assessment.
