Report #91813

[bug\_fix] Resource not accessible by integration \(403\) when pushing to GHCR or creating releases due to GITHUB\_TOKEN defaulting to read-only permissions

Add explicit permissions block at workflow or job level specifying required scopes \(e.g., packages: write for GHCR, contents: write for releases, id-token: write for OIDC\). Alternatively, change repository default to 'Read and write permissions' in Settings > Actions > General if appropriate.

Journey Context:
The workflow successfully built a Docker image but failed when pushing to ghcr.io with 'denied: installation not allowed to Write organization package'. Checking the job logs, the 'Set up job' step showed GITHUB\_TOKEN Permissions with contents: read and packages: read only. This worked previously because the repository was created before February 2023 when GitHub changed the default from permissive to restricted. The initial instinct was to check repository secrets, but the issue was the token's granted permissions scope. Adding permissions: packages: write immediately resolved the push failure without requiring a personal access token.

environment: Repositories created after February 2023 or organizations with restricted token defaults; workflows pushing to GHCR, creating releases, or committing to protected branches · tags: github_token permissions 403 forbidden write access packages:write contents:write · source: swarm · provenance: https://docs.github.com/en/actions/security-guides/automatic-token-authentication\#permissions-for-the-github\_token
