Next.js Framework 16.2.x / 16.3.x < 16.3.6 RCE
critical Nessus Plugin ID 362680
Synopsis
The Next.js Framework on the remote host is affected by a remote code execution vulnerability.Description
The Next.js Framework on the remote host is affected by a remote code execution vulnerability:- The Node.js ImageResponse implementation from next/og is affected by an upstream Satori vulnerability.
Satori does not properly escape certain values before including them in generated SVG output, which can allow crafted values to be interpreted as SVG markup. Applications that pass attacker-controlled values into SVG content, attributes, or styles during image generation can be led to remote code execution.
(CVE-2026-94545)
Exploitation additionally requires that the application uses the Node.js ImageResponse implementation from next/og and passes attacker-controlled values into SVG content, attributes, or styles. Applications using the Edge ImageResponse implementation are not affected. Nessus cannot verify how the application invokes ImageResponse, so this finding is reported as a potential vulnerability.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Next.js Framework version 16.3.6 or later.See Also
