Security Bulletin: Unauthenticated User Registration Could Lead to Remote Code Execution
Summary An attacker could create accounts on an exposed instance without authentication through the user registration API. If an operator had configured newly created accounts to be active immediately, the attacker could then log in as that new user and reach code-execution functionality, which...
Security Bulletin: Arbitrary Code Execution in Python Interpreter Component
Summary A vulnerability in the Python Interpreter component allowed authenticated users to execute arbitrary Python code and escalate privileges to superuser level. An attacker with valid credentials could bypass security controls through the PythonREPLComponent, directly access the database, and...
Security Bulletin: Path Traversal in APIRequest Component via Content-Disposition Header
Summary A path traversal vulnerability existed in the APIRequest component when the "Save to File" feature was enabled. The component extracted filenames from server-controlled Content-Disposition headers without proper sanitization, allowing an attacker-controlled HTTP response to write files to...
