Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A weakness has been identified in NousResearch hermes-agent up to 2026.4.30. This affects the function _scan_memory_content of the file tools/memory_tool.py. This manipulation causes injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Injection vulnerability in NousResearch hermes-agent's _scan_memory_content function within tools/memory_tool.py. The function fails to properly sanitize input when scanning memory content, allowing remote attackers to inject malicious payloads.

MitigationImplement strict input validation and sanitization in _scan_memory_content; restrict network exposure of the hermes-agent service; monitor for indicators of exploitation given public availability of the exploit.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify hermes-agent installation
    Locate the hermes-agent installation directory and confirm the presence of the tools/memory_tool.py file
    Affected if The file tools/memory_tool.py exists in the installation directory
  2. Check installed version
    Examine version metadata or version file within the hermes-agent installation and compare against 2026.4.30
    Affected if The installed version is 2026.4.30 or earlier
  3. Verify vulnerable function exists
    Open tools/memory_tool.py and search for the _scan_memory_content function definition
    Affected if The _scan_memory_content function is present in the file
  4. Determine if memory scanning is accessible
    Review configuration files or access controls to see if the memory scanning functionality can be invoked by remote or untrusted inputs
    Affected if The _scan_memory_content function can be triggered by external or unsanitized input sources

A user is affected if hermes-agent version 2026.4.30 or earlier is installed, the _scan_memory_content function exists in tools/memory_tool.py, and that function can be reached by external or unvalidated input.
