The vulnerability occurs in htdocs/libraries/image-editor/image-edit.php where the 'image_path'/'image_temp' parameter is used unsafely in unlink() calls. However, the vulnerable code resides in the main script execution flow rather than within a named function or class method. PHP's global scope execution (represented as '{main}' in stack traces) doesn't provide a specific function signature. The file path and parameter handling are key indicators, but no discrete function names are identifiable from the provided patch descriptions.
