Is this vulnerability remotely exploitable?

Yes, if a remote user can upload or otherwise provide SVG files that your system processes with SVGO, they can potentially trigger this denial of service. The attack remains local if SVGs are only handled from trusted, internal sources.

What level of access does an attacker need?

An attacker needs the ability to influence an SVG that will be passed through SVGO—commonly via file upload, content submission, or integration points that import third-party SVG assets.

What is the safest general fix pattern?

The safest pattern is to: - Use XML parsing configurations that disable DTDs and entity expansion where possible. - Enforce limits on recursion and expansion when XML entities cannot be fully disabled. - Treat SVGs as untrusted input and validate or sanitize them before optimization.
