False Positivecmd/go: Flag Sanitization Bypass via cgo pkg-config Directives
This advisory does not affect KrakenD
This is a build-time vulnerability in the Go toolchain (
cmd/go) 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)
Disclosed

Description
The allowlist for
#cgo pkg-config: directives permitted options such as --with-path=
and --personality=, and package arguments pointing to local .pc files. A malicious
package could make pkg-config load its own .pc files and inject compiler and linker
flags that the go command would otherwise reject. This is a build-time issue in the Go
toolchain and does not affect KrakenD.
