A zip entry named\n  `../../tmp/evil` therefore landed at `/tmp/evil`. An attacker who could control a `Package.Spec.Source.URL` or `Deployment.URL` archive could induce the fetcher (running as the per-environment pod's `fission-fetcher` sidecar) to write\n  files anywhere that process could reach: into other tenants' `/packages//` directories, into mounted secret/config volumes, or into the fetcher's own binary.\n\n  ### Affected\n\n  - Project: `github.com/fission/fission`\n  - Versions: all up to and including v1.24.0\n  - Audited commit: `647c141`\n  - Component: `pkg/utils/zip.go` (`Unarchive`)\n  - Configuration: default; triggered when the fetcher downloads and extracts a zip archive\n\n  Fix section (paste into the Fix / Patches field)\n\n  Fixed in v1.25.0 by:\n\n  - PR #3444 (commit [`55704aca`](https://github.com/fission/fission/commit/55704aca1b8d6f45bc7c7c2e4805c7e14875","public_affected_ranges":["<= 1.24.0"]}],"null_published_at":"2026-11-04T10:04:27.942Z","source_updated_at":"2026-07-28T20:16:53.000Z","source_disclosed_at":"2026-07-28T20:16:52.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T09:59:04.660Z"}],"next_cursor":null,"snapshot_revision":"40769"}
