CVE-2024-34069: Debian Linux

High severity, CVSS 7.5. EPSS: 3.4% chance of exploitation in the next 30 days.

Werkzeug is a comprehensive WSGI web application library. The debugger in affected versions of Werkzeug can allow an attacker to execute code on a developer's machine under some circumstances. This requires the attacker to get the developer to interact with a domain and subdomain they control, and enter the debugger PIN, but if they are successful it allows access to the debugger even if it is only running on localhost. This also requires the attacker to guess a URL in the developer's application that will trigger the debugger. This vulnerability is fixed in 3.0.3.

Affected products

• Debian Debian Linux: version 11.0 only
• Fedoraproject Fedora: version 38 only; version 40 only
• Palletsprojects Werkzeug: before 3.0.3 (fixed in 3.0.3)
