Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) 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.
2) Inefficient regular expression complexity (CVE-ID: CVE-2025-5889)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions. A remote user can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
