{"id":"CVE-2026-48722","summary":"Nextflow: Incorrect default permissions in the nextflow auth login command","details":"Nextflow is a DSL for data-driven computational pipelines. 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.","aliases":["GHSA-92qf-fcph-v5wr"],"modified":"2026-09-19T03:30:19.058596788Z","published":"2026-09-15T14:07:45.568Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-276","CWE-732"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48722.json"},"references":[{"type":"WEB","url":"https://github.com/nextflow-io/nextflow/releases/tag/v25.10.6"},{"type":"WEB","url":"https://github.com/nextflow-io/nextflow/releases/tag/v26.04.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48722.json"},{"type":"ADVISORY","url":"https://github.com/nextflow-io/nextflow/security/advisories/GHSA-92qf-fcph-v5wr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48722"},{"type":"FIX","url":"https://github.com/nextflow-io/nextflow/commit/41a5f24afec8a6e9769a24cae5e08b5462fbfdc1"},{"type":"FIX","url":"https://github.com/nextflow-io/nextflow/commit/a2813c610a3e7f13d7a0a0b1b543b7ad47586eaa"},{"type":"FIX","url":"https://github.com/nextflow-io/nextflow/pull/7182"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nextflow-io/nextflow","events":[{"introduced":"52052e8ae66ae5ef39ef8391ad0ec3e14f17b21d"},{"introduced":"55f6ff56620db039806ddb98ccd6fe792cebc4ed"},{"fixed":"d48e9beed7fcda769c04652c926f74b9d6efba9e"},{"fixed":"be6245a15427098c43556619de64623efcd05528"},{"fixed":"41a5f24afec8a6e9769a24cae5e08b5462fbfdc1"},{"fixed":"a2813c610a3e7f13d7a0a0b1b543b7ad47586eaa"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"25.09.2-edge"},{"fixed":"25.10.6"},{"introduced":"25.11.0-edge"},{"fixed":"26.04.3"}]}}],"versions":["v26.04.2","v25.10.5","v26.04.1","v26.04.0","v26.03.4-edge","v26.03.3-edge","v26.03.2-edge","v26.03.1-edge","v26.03.0-edge","v26.02.0-edge","v26.01.1-edge","v25.10.4","v25.10.3","v25.10.2","v25.12.0-edge","v25.11.0-edge","v25.10.1","v25.10.0","v25.09.2-edge"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48722.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
