From 6b50f93708c66f68feb322c72350a8cd47f9f671 Mon Sep 17 00:00:00 2001 From: himayday Date: Fri, 29 Aug 2025 15:47:54 +0530 Subject: [PATCH 1/3] Add AutoGPT infinite loop memory exhaustion detection rule (CRE-2025-0165) This CRE rule detects when AutoGPT enters an infinite loop during task execution, repeatedly attempting the same actions without memory of previous attempts. The rule identifies the pattern of repeated command execution, failures, and memory exhaustion that characterizes this high-severity production issue. Key detection patterns: - Repeated thought-command-failure sequences within 60s window - Memory usage approaching critical levels (80%+) - Absence of successful task completion markers - Command retry loops without progression Addresses GitHub issue #129 for AutoGPT high-severity failure reproduction. --- ...togpt-infinite-loop-memory-exhaustion.yaml | 65 +++++++++++++++++++ rules/cre-2025-0165/test.log | 31 +++++++++ rules/tags/tags.yaml | 14 +++- 3 files changed, 109 insertions(+), 1 deletion(-) create mode 100644 rules/cre-2025-0165/autogpt-infinite-loop-memory-exhaustion.yaml create mode 100644 rules/cre-2025-0165/test.log diff --git a/rules/cre-2025-0165/autogpt-infinite-loop-memory-exhaustion.yaml b/rules/cre-2025-0165/autogpt-infinite-loop-memory-exhaustion.yaml new file mode 100644 index 0000000..50a8163 --- /dev/null +++ b/rules/cre-2025-0165/autogpt-infinite-loop-memory-exhaustion.yaml @@ -0,0 +1,65 @@ +rules: + - cre: + id: CRE-2025-0165 + severity: 0 + title: "AutoGPT Infinite Loop Memory Exhaustion" + category: "runtime-problem" + author: Prequel + + description: | + AutoGPT enters an infinite loop during task execution, repeatedly attempting the same + actions without memory of previous attempts.
