A flaw was found in the @backstage/backend-defaults package of Backstage. Improper input validation in cloud storage URL readers allows an attacker with write access to an associated cloud storage bucket to create specially crafted object names. Under certain deployment configurations, these names can collide with and overwrite protected files in the output directory, leading to unauthorized content injection.
