CVE-2026-14617
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk15th percentile — higher than 15% of all known CVEs
Summary
A vulnerability has been detected in NousResearch hermes-agent up to version 2026.4.30. The issue is in the GatewayStreamConsumer._filter_and_accumulate function in gateway/stream_consumer.py, leading to improper handling of case sensitivity. The attack can be initiated remotely but is difficult to exploit.
Risk Assessment
The risk involves a potential remote attack that could lead to improper data filtering, possibly allowing manipulation of the data stream. Due to high complexity and difficulty of exploitation, the risk is limited.
Recommendation
It is recommended to update to a newer version of hermes-agent if available, or implement custom mitigations, as the project has decided not to release a dedicated fix. Monitor publicly disclosed exploits.
