Answer in brief
CVE-2026-18991 records a High severity (CVSS 7.3) vulnerability in nanocoai NanoClaw send_file core.ts path traversal. The current sources do not mark it as known exploited. The current feed maps nanocoai/NanoClaw (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A security vulnerability has been detected in nanocoai NanoClaw up to 2.0.64. This affects an unknown part of the file container/agent-runner/src/mcp-tools/core.ts of the component send_file. Such manipulation leads to path traversal. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
