CVE-2026-5559 Apr 05, 10:15 PyPI LOW POC Monitor

Server-side template injection in PyBlade's AST validation function (_is_safe_ast in sandbox.py) allows authenticated remote attackers to bypass template safety checks and inject arbitrary template code, leading to information disclosure and potential code execution. Affected versions 0.1.8-alpha and 0.1.9-alpha contain improper neutralization of special template elements. Publicly available exploit code exists, though the vendor has not yet responded to disclosure.
