Technical details
A resource exhaustion vulnerability exists in the `AITextSummarizerBlock` of AutoGPT due to improper handling of text chunking in `llm.py`. The `_split_text` function uses user-controllable parameters (`max_tokens` and `overlap`) to determine how text is segmented. By setting `overlap` to `max_tokens - 1`, an attacker can force the `chunk_size` to 1, causing the loop to execute for every word in the input and append overlapping segments to a list. This results in quadratic memory growth; for instance, a 10KB input can trigger 50GB of memory consumption. The vulnerability is tracked as CWE-405 and CWE-770 and is fixed in version 0.6.32.
