A `public-only` token with `write:package` scope, whose owner can read a private package and write to a public package namespace, could mount a blob of the private package into the public package. The private blob, such as a container layer, could then be downloaded by anyone through the public package.\n\n## Affected\n\n- `gitea.dev < 28.3.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
