Detailsinfo

A vulnerability has been found in cyberjunky python-garminconnect up to 0.3.4 and classified as problematic. This vulnerability affects the function Client.dump of the file garminconnect/client.py. The manipulation with an unknown input leads to a permission vulnerability. The CWE definition for the vulnerability is CWE-275. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-54447 since 06/15/2026. The exploitation appears to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1222 by the MITRE ATT&CK project.

Upgrading to version 0.3.5 eliminates this vulnerability.
