From f27208a2f54b863fcce8589ebd245add3827ce68 Mon Sep 17 00:00:00 2001 From: Sahelisaha04 Date: Mon, 1 Sep 2025 00:09:54 +0530 Subject: [PATCH 1/2] Add AutoGPT runaway task loop detection rule (CRE-2025-0171) Implements critical failure detection for AutoGPT autonomous agents that enter runaway task execution loops, causing resource exhaustion and system unresponsiveness. Addresses GitHub issue #129 bounty challenge requirements. Key features: - Detects infinite task retry cycles and recursive task generation - Monitors CPU, memory, and API quota exhaustion patterns - Critical severity (0) for immediate incident response - 4-stage sequence detection with 180s window - Comprehensive mitigation strategies for production environments Test scenario reproduces realistic failure: API rate limiting causing infinite retry loops with escalating resource consumption. --- .../autogpt-runaway-task-loop.yaml | 116 ++++++++++++++++++ rules/cre-2025-0171/test.log | 19 +++ 2 files changed, 135 insertions(+) create mode 100644 rules/cre-2025-0171/autogpt-runaway-task-loop.yaml create mode 100644 rules/cre-2025-0171/test.log diff --git a/rules/cre-2025-0171/autogpt-runaway-task-loop.yaml b/rules/cre-2025-0171/autogpt-runaway-task-loop.yaml new file mode 100644 index 0000000..ad11908 --- /dev/null +++ b/rules/cre-2025-0171/autogpt-runaway-task-loop.yaml @@ -0,0 +1,116 @@ +rules: +- cre: + id: CRE-2025-0171 + severity: 0 + title: AutoGPT Runaway Task Loop with Resource Exhaustion + category: ai-agent-problem + author: Claude Code Assistant + description: | + AutoGPT autonomous agent enters a runaway task execution loop, repeatedly attempting + the same failed operation without termination conditions.
