From 08bcc803efadc3f2bb822f94d513bc0592157f5e Mon Sep 17 00:00:00 2001 From: Eduard van Valkenburg Date: Thu, 16 May 2024 15:02:54 +0200 Subject: [PATCH] Python: Unsafe input handling (#6003) ### Motivation and Context Implements dealing with unsafe content, by doing HTML parsing on variables and function results. Closes: #5889 ### Description Adds parameter `allow_dangerously_set_content` to: - InputVariable - PromptTemplateConfig - PromptTemplateBase The behavior is that if the flag is set to True on the template itself (KernelPromptTemplate, Jinja2PromptTemplate or HandlebarsPromptTemplate) the behavior is the same, no encoding is done on inputs. Otherwise: - variables are encoded by default, this can be switched off using the InputVariables class for that variable. - function output is encoded by default, this can be switched off using the flag in the PromptTemplateConfig, this is not yet possible to do on a per function basis. ### Contribution Checklist - [x] The code builds clean without any errors or warnings - [x] The PR follows the [SK Contribution Guidelines](https://github.com/microsoft/semantic-kernel/blob/main/CONTRIBUTING.md) and the [pre-submission formatting script](https://github.com/microsoft/semantic-kernel/blob/main/CONTRIBUTING.md#development-scripts) raises no violations - [x] All unit tests pass, and I have added new tests where possible - [x] I didn't break anyone :smile: --- .../decisions/0040-chat-prompt-xml-support.md | 6 +- python/semantic_kernel/const.py | 4 + .../semantic_kernel/contents/chat_history.py | 16 +- .../contents/chat_message_content.py | 13 +- .../streaming_chat_message_content.py | 3 - .../semantic_kernel/contents/text_content.py | 3 +- .../functions/kernel_arguments.py | 8 +- .../functions/kernel_function.py | 7 +- .../functions/kernel_function_from_prompt.py | 8 +- python/semantic_kernel/kernel.py | 10 +- .../sequential_planner/sequential_planner.py | 5 +- .../handlebars_prompt_template.py | 24 +- .../prompt_template/input_variable.py | 13 + .../prompt_template/jinja2_prompt_template.py | 24 +- .../prompt_template/kernel_prompt_template.py | 69 +- .../prompt_template/prompt_template_base.py | 61 ++ .../prompt_template/prompt_template_config.py | 39 +- .../utils/handlebars_system_helpers.py | 2 +- .../utils/jinja2_system_helpers.py | 2 +- .../utils/template_function_helpers.py | 11 +- .../template_engine/blocks/code_block.py | 3 +- .../tests/unit/contents/test_chat_history.py | 72 ++- .../contents/test_chat_message_content.py | 8 +- .../test_streaming_chat_message_content.py | 8 +- .../test_kernel_function_from_method.py | 18 +- .../test_kernel_function_from_prompt.py | 9 +- python/tests/unit/kernel/test_kernel.py | 7 +- .../prompt_template/semantic-kernel-tests.txt | 4 +- .../test_handlebars_prompt_template.py | 14 +- .../test_handlebars_prompt_template_e2e.py | 3 +- .../test_jinja2_prompt_template_e2e.py | 3 +- .../test_kernel_prompt_template.py | 146 +---- .../test_prompt_template_e2e.py | 597 +++++++++++++++--- .../template_engine/blocks/test_code_block.py | 2 +- 34 files changed, 869 insertions(+), 353 deletions(-) create mode 100644 python/semantic_kernel/const.py diff --git a/docs/decisions/0040-chat-prompt-xml-support.md b/docs/decisions/0040-chat-prompt-xml-support.md index 42e77becc5..1a1bf19db7 100644 --- a/docs/decisions/0040-chat-prompt-xml-support.md +++ b/docs/decisions/0040-chat-prompt-xml-support.md @@ -109,13 +109,13 @@ Chosen option: "HTML encode all inserted content by default.", because it meets This solution work as follows: 1.
