CVE-2026-25680 CVE Medium False Positive

html: Denial of Service via Cubic Complexity During Tree Construction

This advisory does not affect KrakenD

KrakenD is an API gateway and does not use golang.org/x/net/html to parse HTML content from user requests. The vulnerable HTML parsing code path is never invoked during KrakenD operation.

Addressed through routine dependency maintenance in CE 2.13.6 and EE 2.13.4.

Component

golang.org/x/net (html)

Disclosed

May 26, 2026

Description

Go’s golang.org/x/net/html package uses a cubic-complexity algorithm when constructing the HTML parse tree for certain pathological inputs. A crafted HTML document can cause the parser to perform an excessive amount of work, leading to denial of service.
