It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix.\n\nAffected versions:\nBOSH Director: All versions prior to v282.1.12","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:H","score":6.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:C/C:N/I:H/A:N","score":5.0},"cwes":["CWE-284"],"references":["https://www.cloudfoundry.org/blog/cve-2026-41704-compromised-vm-can-make-arbitrary-blobstore-deletes/"],"products":["cloud_foundry:bosh"],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-41704","score":0.00083,"percentile":0.00235,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
