Submit #558415: web-arena-x webarena <=0.2.0 Code Injectioninfo

Titleweb-arena-x webarena <=0.2.0 Code Injection
DescriptionWebArena is a standalone, self-hostable web environment for building LLM autonomous agents. In the WebArena project, specifically in the evaluators.py file (https://github.com/web-arena-x/webarena/blob/main/evaluation_harness/evaluators.py#L266), there is a critical vulnerability. The code checks if the "target_url" starts with "func" and if so, extracts a substring, replaces a value, and then passes it to the "eval()" function for execution. Since "eval()" is used with user-supplied input (as demonstrated by creating a config with "target_url= 'func:import('os').system('rm -f /path/to/sensitive/file')'"), it poses a Remote Code Execution (RCE) risk. This allows attackers to execute arbitrary code with the privileges of the running application, potentially leading to data loss, service outages, or malware installation. It aligns with CWE-94.
