Prior to versions 8.0.79, 9.0.22, and 9.1.10, WorkloadManagementSystem/Utilities/PilotWrapper.py pilotWrapperScript uses ssl._create_unverified_context to download the second-stage pilot.tar archive without TLS certificate verification and downloads the reference checksum through the same unvalidated channel. An attacker able to redirect or intercept a grid site's network traffic through DNS or routing manipulation can substitute both the executable pilot code and its checksum, causing arbitrary code to run in the pilot context with access to pilot proxy credentials. The fixed implementation validates the server certificate through system trust and X509_CERT_DIR or the grid certificate directory. This issue is fixed in versions 8.0.79, 9.0.22, and 9.1.10.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-295"],"references":["https://github.com/DIRACGrid/DIRAC/commit/68029dfb5ddd8b1e4106851f8e37370aa80ac7ae","https://github.com/DIRACGrid/DIRAC/commit/92e2e26c63b964b8499bee5e9c2e2821a36eac56","https://github.com/DIRACGrid/DIRAC/commit/b332c437d064f66ee46f5b45a90a9f7c4bace38d","https://github.com/DIRACGrid/DIRAC/releases/tag/v8.0.79","https://github.com/DIRACGrid/DIRAC/releases/tag/v9.0.22"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-61668","score":0.00396,"percentile":0.33569,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vg99-gr89-qhw9","url":"https://osv.dev/vulnerability/GHSA-vg99-gr89-qhw9","summary":"DIRAC: Pilot code downloaded over unverified HTTPS connection","modified":"2026-07-23T15:11:17.011634694Z","packages":[{"ecosystem":"PyPI","name":"dirac","purl":"pkg:pypi/dirac","ranges":[">=6.20.1 <8.0.79"],"fixed":["8.0.79"]},{"ecosystem":"PyPI","name":"dirac","purl":"pkg:pypi/dirac","ranges":[">=8.1.0a1 <9.0.22"],"fixed":["9.0.22"]},{"ecosystem":"PyPI","name":"dirac","purl":"pkg:pypi/dirac","ranges":[">=9.1.0 <9.1.10"],"fixed":["9.1.10"]}]},{"id":"PYSEC-2026-3464","url":"https://osv.dev/vulnerability/PYSEC-2026-3464","summary":"DIRAC: Pilot code downloaded over unverified HTTPS connection","modified":"2026-07-23T15:00:12.427008868Z","packages":[{"ecosystem":"PyPI","name":"dirac","purl":"pkg:pypi/dirac","ranges":[">=6.20.1 <8.0.79",">=8.1.0a1 <9.0.22",">=9.1.0 <9.1.10"],"fixed":["8.0.79","9.0.22","9.1.10"]}]}],"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).
