Last updated on: 2026-09-03

Assigner: VulDB

Description
A vulnerability was found in NousResearch hermes-agent 0.18.0. This vulnerability affects the function resourceBufferFromUrl of the file apps/desktop/electron/main.ts of the component Electron Main Process. Performing a manipulation results in allocation of resources. The attack may be initiated remotely. copyImageFromUrl() entry point no longer reachable on current main. That function did exist at v2026.8.3 but was removed by v2026.8.19. The modern copy-image path is Electron-native event.sender.copyImageAt().

Executive Summary

This vulnerability exists in NousResearch hermes-agent 0.18.0 where the function resourceBufferFromUrl in apps/desktop/electron/main.ts improperly handles resource allocation. An attacker can manipulate this to cause resource exhaustion remotely. The copyImageFromUrl() function was removed between versions 2026.8.3 and 2026.8.19, and the modern path uses Electron's event.sender.copyImageAt().

Impact Analysis

This vulnerability could lead to denial-of-service conditions by consuming excessive system resources. It may cause application crashes or slowdowns, particularly in environments using the affected hermes-agent version. Users might experience degraded performance or unexpected termination of the application.

Mitigation Strategies

Update hermes-agent to a version where the vulnerable function resourceBufferFromUrl has been removed or replaced. Specifically, ensure you are using a version newer than v2026.8.19 where the function was removed. Alternatively, switch to using the Electron-native event.sender.copyImageAt() method for image copying operations.
