CVE-2026-14628
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 · uneditedA vulnerability was detected in NousResearch hermes-agent up to 2026.5.16. This impacts the function extract_media of the file gateway/platforms/base.py of the component Live Webhook Endpoint. Performing a manipulation results in path traversal. The attack may be initiated remotely. The exploit is now public and may be used. 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 confidencePath traversal vulnerability in the extract_media function of gateway/platforms/base.py within the Live Webhook Endpoint of NousResearch hermes-agent. An attacker can manipulate file path inputs to access files outside the intended directory through the webhook, potentially exposing sensitive system files.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify hermes-agent installationLocate the hermes-agent installation directory and verify the presence of the gateway/platforms/base.py fileAffected if The file gateway/platforms/base.py exists in the installation and contains an extract_media function
-
Verify Live Webhook Endpoint configurationExamine the hermes-agent configuration files (e.g., config.yaml, settings.json, or environment variables) to determine if the Live Webhook Endpoint feature is enabledAffected if The Live Webhook Endpoint is enabled and accessible
-
Check extract_media function implementationReview the extract_media function in gateway/platforms/base.py for path traversal vulnerabilities - look for file path operations without proper validation using realpath() or equivalent canonicalizationAffected if The function accepts user-controlled file paths without validating they are within allowed directories
-
Determine webhook exposureIdentify network exposure of the webhook endpoint (check for open ports, reverse proxy configurations, or firewall rules)Affected if The webhook endpoint is exposed to untrusted networks without network-level access controls
-
Check installed versionRun package manager commands (pip show, git tag, or version file inspection) to obtain the hermes-agent versionAffected if The installed version predates the fix and matches the vulnerable code path in gateway/platforms/base.py
A user is affected if hermes-agent is installed with the vulnerable extract_media function in gateway/platforms/base.py and the Live Webhook Endpoint is enabled and accessible

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation using realpath() to canonicalize and verify file paths are within allowed directories, combined with an allowlist approach for permitted base paths.
