CVE-2026-86995: n8n

Medium severity, CVSS 4.3. EPSS: 0.4% chance of exploitation in the next 30 days.

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node validated the repository parameter for fetch or pull, but setUpstream wrote a branch..remote value into repository configuration without validating it. A later fetch or pull resolved the remote from that configuration instead of the checked parameter. An authenticated workflow editor could therefore point Git at any local repository readable by the n8n process and receive its contents through packages/nodes-base/nodes/Git/GenericFunctions.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.

Affected products

• n8n n8n: before 1.123.76 (fixed in 1.123.76); from 2.0.0, before 2.37.7 (fixed in 2.37.7); from 2.38.0, before 2.38.2 (fixed in 2.38.2)
