Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) XML External Entity injection (CVE-ID: CVE-2026-24400)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to `org.assertj.core.util.xml.XmlStringPrettyFormatter`: the `toXmlDocument(String)` method initializes `DocumentBuilderFactory` with default settings, without disabling DTDs or external entities. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
2) Inefficient regular expression complexity (CVE-ID: CVE-2026-26996)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions within "minimatch" function. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
3) Use of cache containing sensitive information (CVE-ID: CVE-2026-27205)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to when the session object is accessed, Flask should set the Vary: Cookie header. The logic instructs caches not to cache the response, as it may contain information specific to a logged in user. This is handled in most cases, but some forms of access such as the Python in operator were overlooked. The severity and risk depend on the application being hosted behind a caching proxy that doesn't ignore responses with cookies, not setting a Cache-Control header to mark pages as private or non-cacheable, and accessing the session in a way that only touches keys without reading values or mutating the session. A remote attacker can gain unauthorized access to sensitive information on the system.
4) Improper Handling of Windows Device Names (CVE-ID: CVE-2026-27199)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to the "safe_join" function allows Windows device names as filenames if when preceded by other path segments. A remote attacker can cause reading of the file to hang indefinitely.
