Vulnerability investigation

Prioritize by applicability, impact, and exploitation evidence

CISA KEV status could not be verified from the available evidence. NVD rates the technical severity medium at CVSS 4.3. These are public vulnerability signals, not proof that a specific environment runs an affected version.

Exploitation status

KEV status unavailable

The KEV source did not return a conclusive status.

30-day exploitation likelihood

Unavailable

FIRST EPSS did not return a score.

NVD CPE / CISA product metadata

Product names are candidate applicability pivots. Confirm exact deployed versions and vendor ranges before remediation decisions.

What remains unknown

Whether your environment runs an affected product and version is not established by this public lookup.
Reachability, compensating controls, and successful exploitation in a specific environment are not checked.
CISA KEV status is unavailable and must be retried before drawing an exploitation conclusion.
No locally ingested public report supplies exploit, actor, or campaign context for this CVE.

What this is

n8n before 1.123.69, 2.33.4, and 2.34.1 contains an SSRF protection bypass in the OAuth2 credential authorization-code-to-access-token exchange. While OAuth2 discovery and dynamic-client-registration requests use n8n's SSRF-protected HTTP client, the token exchange uses a separate client with no SSRF guard. A user with credential-creation permissions can set the access-token URL to an internal address and complete the OAuth2 flow, causing n8n to send a fixed-shape token-exchange POST to that target and reflect its response body back to the attacker (limited to what the target returns to this specific request).
