Title
Emmett has a path traversal in internal assets handler
Summary
Emmett is a full-stack Python web framework designed with simplicity. From 2.5.0 to before 2.8.1, the RSGI static handler for Emmett's internal assets (/__emmett__ paths) is vulnerable to path traversal attacks. An attacker can use ../ sequences (eg /__emmett__/../rsgi/handlers.py) to read arbitrary files outside the assets directory. This vulnerability is fixed in 2.8.1.
Severity ?

CVE-2026-25577 (GCVE-0-2026-25577)

Title
Emmett has an Unhandled CookieError Exception Causing Denial of Service
Summary
Emmett is a framework designed to simplify your development process. Prior to 1.3.11, the cookies property in mmett_core.http.wrappers.Request does not handle CookieError exceptions when parsing malformed Cookie headers. This allows unauthenticated attackers to trigger HTTP 500 errors and cause denial of service. This vulnerability is fixed in 1.3.11.
Severity ?
7.5 (High)
