High CVSS 7.1

CVE-2026-77071

NVD analysis in progress

n8n before 1.123.69, 2.33.4, and 2.34.1 contains a PostgREST filter injection vulnerability in the Supabase node's Row Get Many, Delete, and Update operations, which built filter queries by concatenating an expression-bindable value without escaping. An attacker could inject a condition that widened the filter to match every row, turning an intended single-row operation into full-table disclosure, deletion, or modification.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim. It also depends on circumstances the attacker does not control.
Impact
The vector describes no direct impact on data or availability.
Weakness
Unescaped input is placed into an SQL query, letting the attacker read or alter the database (SQL injection).
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle. Start with the instances exposed to the internet.
