From 1.16.1 until 35.9.0, 38.6.0, and 41.0.0rc1, the /credentials/signurl endpoint reads X-Rucio-Account instead of the account stored in request.environ['issuer'] by token authentication. Any authenticated low-privilege user can supply root as the header value and pass the root-only get_signed_url permission check. The server then returns a presigned read, write, or delete URL for an attacker-selected object using stored S3, GCS, or Swift credentials, and X-Rucio-VO can select another tenant in multi-VO deployments. This permits data disclosure, modification, deletion, and cross-tenant access on cloud-backed RSEs. This issue is fixed in versions 35.9.0, 38.6.0, and 41.0.0rc1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-58273https://github.com/rucio/rucio/security/advisories/GHSA-5j9r-fx4x-rpvghttps://github.com/rucio/rucio/commit/64c0e6a6a93ae88427ff3b7d77532ce08c8a69echttps://github.com/rucio/rucio/commit/8bdc38994a8766658d0314d36afc104c9242c96fhttps://github.com/rucio/rucio/commit/8d9ba31514e6f5dca32b8c1db4738582cb37ec3ahttps://github.com/rucio/rucio/releases/tag/35.9.0https://github.com/rucio/rucio/releases/tag/38.6.0https://github.com/rucio/rucio/releases/tag/41.0.0rc1#rucio#CVE_2026_58273#bot", "url": "https://infosec.exchange/users/cve/statuses/117566101240582401"}, {"timestamp": "2026-11-05T22:18:49.230Z", "date_only": false, "value": "2026-11-05T22:18:49.230", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58273", "record": "FKIE_CVE-2026-58273", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-06T04:31:30.349Z", "date_only": false, "value": "2026-11-06T04:31:30.349316Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mzmkezlc5n2k", "record": "CVE-2026-58273", "field": "creation_timestamp", "uuid": "8f4d191d-175e-4ebe-b85f-e6d621fc073a", "content": "\ud83d\udfe0 CVE-2026-58273 - High (8.1)\n\nRucio is a scientific data management framework.
