CVE-2026-8056: Parameter Injection Vulnerability in API Graph Execution Engine

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.53% (FIRST EPSS).
  • 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.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

IBM Langflow OSS 1.0.0 through 1.10.0 allows authenticated users to override component parameters at runtime via the API. A critical security flaw exists in the parameter filtering mechanism within the `apply_tweaks()` function.
