CVE-2026-104328: Langflow OSS is affected by multiple vulnerabilities

HighCVSS 8.8 · v3.1—No exploit No fix recorded

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: 0.70% (FIRST EPSS); higher than 53.7% 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.
  • 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 1.12.3 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
