Wesnoth 1.4.x and 1.5 < 1.5.11 - Remote Code Execution via Python AI Module Sandbox Escape
The Python AI module in Wesnoth 1.4.x and 1.5 before 1.5.11 allows remote attackers to escape the sandbox and execute arbitrary code by using a whitelisted module that imports an unsafe module, then using a hierarchical module name to access the unsafe module through the whitelisted module.
