Provenance
Supply chain provenance
Status for the latest visible version.
No SLSA provenance
npm registry signatures
gitHead linked
Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| npm-metadata | no-description | AI (npm-metadata): Backstage monorepo packages often have minimal metadata; this is a library component with proper repo documentation. | ai | |
| provenance | no-provenance | AI (provenance): Provenance is not yet standard practice; absence is not a security concern for established ecosystem packages. | ai | |
| dependencies | unvetted-dep:@backstage/plugin-app | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai | |
| dependencies | unvetted-dep:@backstage/core-components | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai | |
| dependencies | unvetted-dep:@backstage/frontend-app-api | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai | |
| dependencies | unvetted-dep:@backstage/config | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai | |
| dependencies | unvetted-dep:@react-hookz/web | AI (dependencies): @react-hookz/web is a well-known React hooks library; legitimate dependency for a frontend package. | ai | |
| bogus-package | bogus-package | AI (bogus-package): Monorepo sub-packages commonly lack standalone descriptions/keywords/README code blocks; not indicative of spam or malice for @backstage/* packages. | ai | |
| phantom-deps | phantom-dep:@react-hookz/web | AI (phantom-deps): Declared in dependencies and used in config/tooling context; not a security concern for this package. | ai | |
| dependencies | unvetted-dep:@backstage/frontend-plugin-api | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai | |
| dependencies | unvetted-dep:@backstage/errors | AI (dependencies): Official @backstage/* package from the Backstage monorepo; legitimate and well-established dependency. | ai |
