These have been logged in raw form since https://github.com/softwarepub/hermes/commit/7f64f102e916c76dc44404b77ab2a80f5a4e59b1 in: https://github.com/softwarepub/hermes/blob/3a92f42b2b976fdbc2c49a621de6d665364a7cee/src/hermes/commands/cli.py#L66\n\nIf users provide sensitive data such as API tokens (e.g., via `hermes deposit -O invenio_rdm.auth_token SECRET`), these are written to the log file in plain text, making them available to whoever can access the log file.\n\n### Impact\n\nAs currently, `hermes.log` is not yet uploaded automatically as an artifact in CI, this vuln impacts:\n\n- local users working on shared access computers, where logs may be written to a commonly accessible file system\n- CI users whose CI logs are accessible to others, e.g., through group or organization rights\n\nPotentially, if the changes merged from https://github.com/softwarepub/ci-templates/pull/13 are merged into `ci-templates` via https://github.com/softwarepub/ci-templates/pull/14, this would automate the disclosure of Invenio auth tokens at least for all CI runs against Invenio instances!\n\n### Patches\n\nThis has been patched in [`hermes` 0.9.1](TODO) by masking all values passed using `-O`.\n\n### Workarounds\n\nUpgrade to `hermes` >= 0.9.1.","published":"2026-01-12T22:00:30.175Z","modified":"2026-08-12T03:51:13.727135250Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N"},"epss":{"score":0.00175,"percentile":0.07222,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"hermes","fixedVersion":"0.9.1"}],"fix":{"url":"https://github.com/softwarepub/hermes/commit/7f64f102e916c76dc44404b77ab2a80f5a4e59b1","label":"softwarepub/hermes@7f64f10"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22798.json"},{"type":"ADVISORY","url":"https://github.com/softwarepub/hermes/security/advisories/GHSA-jm5j-jfrm-hm23"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22798"},{"type":"FIX","url":"https://github.com/softwarepub/hermes/commit/7f64f102e916c76dc44404b77ab2a80f5a4e59b1"},{"type":"FIX","url":"https://github.com/softwarepub/hermes/commit/90cb86acd026e7841f2539ae7a1b284a7f263514"},{"type":"PACKAGE","url":"https://github.com/softwarepub/hermes"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.727135250Z"}}
