| عنوان | RubyLouvre avalon 0.9.9 - 2.2.10 Code Injection / Prototype Pollution |
|---|
| الوصف | Avalon MVVM framework stores template filters in a plain object (avalon.filters = {}) and accesses them via bracket notation without hasOwnProperty protection. Attackers can access Object.prototype properties through filter names like __proto__ or constructor. Combined with the template parser's use of new Function() for expression compilation, this enables Remote Code Execution when an attacker controls template content. Project is unmaintained since 2019 but still widely used in legacy systems. |
