CVE-2026-97043
CVE
High
False Positivecmd/go: Code Execution via Escaped Quotes in //go:cgo_ldflag
This advisory does not affect KrakenD
This is a build-time vulnerability in the Go toolchain (
cmd/go and cmd/compile) that requires
compiling a malicious package. KrakenD distributes pre-compiled binaries and never
invokes the Go toolchain at runtime, so the gateway is not exposed. If you compile
KrakenD Enterprise plugins, build them with the krakend/builder-ee image of version
3.0.4 or 2.13.14, which ships the fixed toolchain.Addressed through routine dependency maintenance in CE 3.0.4 and EE 3.0.4, 2.13.14.
Component
Go toolchain (cmd/go, cmd/compile)
Disclosed
Nov 12, 2026
Description
The compiler and the
go command parsed //go:cgo_ldflag directives by splitting on
quote characters without handling backslash escapes. A malicious package could smuggle
disallowed linker flags past validation and execute code at build time, or make the go
command panic. This is a build-time issue in the Go toolchain and does not affect
KrakenD.
