CVE-2026-5831: Agions taskflow-ai terminal_execute handlers.ts os command injection
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 68.7% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Agions taskflow-ai 2.1.9.
Low priority for now. Upgrade to Agions taskflow-ai 2.1.9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
A security flaw has been discovered in Agions taskflow-ai up to 2.1.8. This impacts an unknown function of the file src/mcp/server/handlers.ts of the component terminal_execute. Performing a manipulation results in os command injection. The attack is possible to be carried out remotely. Upgrading to version 2.1.9 will fix this issue. The patch is named c1550b445b9f24f38c4414e9a545f5f79f23a0fe. Upgrading the affected component is recommended. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
