From 25.09.2-edge until 25.10.6 and 26.04.3, nextflow auth login writes Seqera Platform OIDC bearer tokens to ${NXF_HOME:-~/.nextflow}/seqera-auth.config through AuthCommandImpl.writeConfig in plugins/nf-tower/src/main/io/seqera/tower/plugin/auth/AuthCommandImpl.groovy without setting restrictive file permissions, allowing the default umask 022 to create the file with mode 0644. On a multi-user POSIX host, a local user who can traverse the victim's home directory can read seqera-auth.config and impersonate the victim against Seqera Platform within the token's scope. Single-user systems and headless CI runners that do not use the interactive login flow are not affected. This issue is fixed in 25.10.6 and 26.04.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-276","CWE-732"],"references":["https://github.com/nextflow-io/nextflow/commit/41a5f24afec8a6e9769a24cae5e08b5462fbfdc1","https://github.com/nextflow-io/nextflow/commit/a2813c610a3e7f13d7a0a0b1b543b7ad47586eaa","https://github.com/nextflow-io/nextflow/pull/7182","https://github.com/nextflow-io/nextflow/releases/tag/v25.10.6","https://github.com/nextflow-io/nextflow/releases/tag/v26.04.3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-48722","score":0.00142,"percentile":0.03504,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-92qf-fcph-v5wr","url":"https://osv.dev/vulnerability/GHSA-92qf-fcph-v5wr","summary":"nextflow auth login command has incorrect default permissions","modified":"2026-06-25T22:11:29.527989Z","packages":[{"ecosystem":"Maven","name":"io.nextflow:nextflow","purl":"pkg:maven/io.nextflow/nextflow","ranges":[">=25.09.2-edge <25.10.6"],"fixed":["25.10.6"]},{"ecosystem":"Maven","name":"io.nextflow:nextflow","purl":"pkg:maven/io.nextflow/nextflow","ranges":[">=26.00.0-edge <26.04.3"],"fixed":["26.04.3"]}]}],"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).
