CVE-2026-118642: n8n before 1.123.85, 2.43.5, and 2.44.1 Credential Permission Check Bypass via Inline Sub-Workflows

MediumCVSS 5.1 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 20/100)

  • 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: 0.21% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: n8n-io n8n 1.123.85, 2.43.5, 2.44.1.

Low priority for now. Upgrade to n8n-io n8n 1.123.85, 2.43.5, 2.44.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

n8n before 1.123.85, 2.43.5, and 2.44.1 contains an authorization bypass vulnerability that allows authenticated members to use inaccessible credentials through inline sub-workflow nodes with non-boolean disabled values. Attackers knowing a credential id can run Execute Workflow nodes in inline JSON mode that skip the permission check and send decrypted credentials to attacker-controlled servers.
