{"cve":"CVE-2026-54447","nvd":{"published":"2026-09-14T20:16:46.290","modified":"2026-09-30T17:51:56.193","status":"Deferred","description":"garminconnect is a Python 3 API wrapper for Garmin Connect that retrieves statistics and manages activities. Prior to 0.3.5, garminconnect/client.py Client.dump creates the OAuth token directory and garmin_tokens.json without explicit owner-only modes, so a permissive umask such as 022 can leave the directory mode at 0755 and the token file mode at 0644. garmin_tokens.json contains di_refresh_token, and another unprivileged user on a shared Linux or macOS host can read the token and obtain persistent access to the victim's Garmin Connect account, including health, fitness, activity, and device data. The Garmin.login tokenstore path is affected, and a pre-existing loosely permissioned token file remains exposed until rewritten or manually restricted. This issue is fixed in version 0.3.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","score":8.4},"cwes":["CWE-732"],"references":["https://github.com/cyberjunky/python-garminconnect/commit/8256b577190b446e279c81b845d8e27d0ea1fbf5","https://github.com/cyberjunky/python-garminconnect/releases/tag/0.3.5","https://github.com/cyberjunky/python-garminconnect/security/advisories/GHSA-wjhr-76vg-2hvc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-54447","score":0.00151,"percentile":0.04235,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wjhr-76vg-2hvc","url":"https://osv.dev/vulnerability/GHSA-wjhr-76vg-2hvc","summary":"garminconnect Has Insecure Permission Assignment for Garmin OAuth Token Store","modified":"2026-07-23T15:11:39.561071147Z","packages":[{"ecosystem":"PyPI","name":"garminconnect","purl":"pkg:pypi/garminconnect","ranges":["<0.3.5"],"fixed":["0.3.5"]}]},{"id":"PYSEC-2026-3467","url":"https://osv.dev/vulnerability/PYSEC-2026-3467","summary":"garminconnect Has Insecure Permission Assignment for Garmin OAuth Token Store","modified":"2026-07-23T15:00:12.561702450Z","packages":[{"ecosystem":"PyPI","name":"garminconnect","purl":"pkg:pypi/garminconnect","ranges":["<0.3.5"],"fixed":["0.3.5"]}]}],"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).
