CVE-2026-14617
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
A security vulnerability has been detected in the Streaming Reasoning Tag Filter component of NousResearch hermes-agent up to version 2026.4.30, involving improper handling of case sensitivity in the GatewayStreamConsumer._filter_and_accumulate function. The attack can be initiated remotely but is difficult to exploit due to high complexity. The project decided not to implement a dedicated fix, citing maintenance costs.
Risk Assessment
The risk for the organization is a potential remote attack that could lead to unauthorized access or data manipulation, but due to high complexity and difficulty of exploitation, the likelihood of a successful attack is low.
Recommendation
It is recommended to monitor publicly available exploits and consider implementing temporary mitigations such as input filtering or access restrictions to the component until an update is available.
Original NVD description (English source)
A security vulnerability has been detected in NousResearch hermes-agent up to 2026.4.30. Affected is the function GatewayStreamConsumer._filter_and_accumulate of the file gateway/stream_consumer.py of the component Streaming Reasoning Tag Filter. The manipulation leads to improper handling of case sensitivity. The attack may be initiated remotely. The attack's complexity is rated as high. The exploitability is told to be difficult. The exploit has been disclosed publicly and may be used. The project decided to not implement a dedicated fix: "[T]he analysis and the fix are both sound. It just lands below the bar for the maintenance cost of a duplicated scrub path."
