Descriptions

cmd/go in Go before 1.16.14 and 1.17.x before 1.17.7 can misinterpret branch names that falsely appear to be version tags. This can lead to incorrect access control if an actor is supposed to be able to create branches but not tags.

cmd/go en Go versiones anteriores a 1.16.14 y versiones 1.17.x anteriores a 1.17.7, puede malinterpretar nombres de rama que falsamente parecen ser etiquetas de versión. Esto puede conllevar a un control de acceso incorrecto si supone que un actor puede crear ramas pero no etiquetas

A flaw was found in the go package of the cmd library in golang. The go command could be tricked into accepting a branch, which resembles a version tag. This issue could allow a remote unauthenticated attacker to bypass security restrictions and introduce invalid or incorrect tags, reducing the integrity of the environment.
