OpenClaw Feishu Webhook Vulnerability: Unauthenticated Command Execution
2 rules 1 TTPOpenClaw versions before 2026.4.15 are vulnerable to unauthenticated webhook or card-action traffic due to missing encryption key configuration and improper handling of card-action callbacks, potentially allowing network-triggered access to OpenClaw command handling without Feishu signature or replay protection.
OpenClaw: Unauthorized Profile Reset via browser.request
2 rules 1 TTPOpenClaw version 2026.3.22 allows authenticated users with `operator.write` access to the `browser.request` method to reset persistent browser profiles via a `POST /reset-profile` request due to a missing check in the persistent-profile mutation classifier, leading to data loss and service disruption.
Optimole WordPress Plugin Stored XSS Vulnerability
2 rules 1 TTP 1 CVEThe Optimole WordPress plugin before version 4.2.3 is vulnerable to stored cross-site scripting (XSS) due to insufficient input sanitization and output escaping on the 's' parameter (srcset descriptor) in the unauthenticated /wp-json/optimole/v1/optimizations REST endpoint, allowing unauthenticated attackers to inject arbitrary web scripts.
Pipecat Remote Code Execution via Pickle Deserialization in LivekitFrameSerializer
2 rules 1 TTP 1 CVEA critical vulnerability, CVE-2025-62373, exists in Pipecat's LivekitFrameSerializer where the deserialize() method uses Python's pickle.loads() on WebSocket data without validation, allowing a malicious WebSocket client to execute arbitrary code on the Pipecat server if LivekitFrameSerializer is explicitly enabled.
