CVE-2025-32394Public exploitNetwork attack vector

Service interruption via quadratic text-chunk amplification

Published Jun 26, 2026 · Updated Jun 26, 2026

Denial of service in AutoGPT before 0.6.32 allows remote authenticated users to exhaust server memory through crafted summarizer input. AITextSummarizerBlock's _split_text function subtracts user-controlled overlap from max_tokens, then repeatedly stores overlapping chunks without bounding total allocation. An authenticated workflow user can set overlap one below max_tokens, causing quadratic amplification that exhausts memory and interrupts the service.
