Which of the following functions or classes contains a `CWE-918: Server-Side Request Forgery (SSRF)` vulnerability?

  A) check
  B) post

Name the function or class in this code that contains a `CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')` vulnerability.
Answer: put
system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

Which of the following CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-215: Insertion of Sensitive Information Into Debugging Code
  B) CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
  C) CWE-732: Incorrect Permission Assignment for Critical Resource
  D) CWE-918: Server-Side Request Forgery (SSRF)
  E) CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
  F) CWE-1004: Sensitive Cookie Without 'HttpOnly' Flag
Answer: B
system: You are an expert security code reviewer. You will be shown a source code file along with a multiple-choice question listing several function or class names from that file. Your task is to identify which one contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the single letter of the correct option, wrapped in \boxed{...}. Example: `\boxed{B}`. Output the boxed letter ONLY -- no explanation, no other text.

Which of the following functions or classes contains a `CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')` vulnerability?

  A) get_raw_df
  B) unpack_tar_file
  C) load_raw_data_to_df
Answer: B
system: You are an expert security code reviewer. You will be shown a source code file. Your task is to name the single function or class that contains the specified CWE vulnerability.
