Backstage is an open framework for building developer portals. Prior to 0.3.10 in @backstage/plugin-scaffolder-backend-module-bitbucket-cloud and 0.2.25 in @backstage/plugin-scaffolder-backend-module-bitbucket-server, the Bitbucket pull-request Scaffolder actions did not sufficiently validate filesystem paths. An authenticated user who can execute an eligible template and influence an allowed Bitbucket repository could affect paths outside the expected working area, potentially compromising backend confidentiality, integrity, or availability. This issue is fixed in @backstage/plugin-scaffolder-backend-module-bitbucket-cloud 0.3.10 and @backstage/plugin-scaffolder-backend-module-bitbucket-server 0.2.25.

 https://vulnerability.circl.lu/vuln/ghsa-g8rx-f7m5-7794 GHSA-g8rx-f7m5-7794 — Backstage has iImproper filesystem validation in Bitbucket pull-request scaffolder actions 2026-10-09T13:11:49.861846+00:00

Affected: npm: @backstage/plugin-scaffolder-backend-module-bitbucket-cloud, npm: @backstage/plugin-scaffolder-backend-module-bitbucket-server

### Impact

An authenticated user who can execute an eligible template and influence an allowed Bitbucket repository could affect filesystem paths outside the expected working area. Depending on the backend deployment, this could compromise backend confidentiality, integrity, or availability.

### Patches

- `@backstage/plugin-scaffolder-backend-module-bitbucket-cloud` version `0.3.10` - `@backstage/plugin-scaffolder-backend-module-bitbucket-server` version `0.2.25`

### Workarounds

- Restrict execution of affected Scaffolder templates to trusted users. - Avoid templates that accept user-controlled target repositories for these actions.
