7.5 · HIGHOverview
CVE-2026-32309 is a high-severity vulnerability affecting cryptomator cryptomator. It was published on March 20, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Cryptomator encrypts data being stored on cloud infrastructure. Prior to version 1.19.1, the Hub-based unlock flow explicitly supports hub+http and consumes Hub endpoints from vault metadata without enforcing HTTPS. As a result, a vault configuration can drive OAuth and key-loading traffic over plaintext HTTP or other insecure endpoint combinations. An active network attacker can tamper with or observe this traffic. Even when the vault key is encrypted for the device, bearer tokens and endpoint-level trust decisions are still exposed to downgrade and interception. This issue has been patched in version 1.19.1.
Remediation
Check the references section for vendor advisories and patches from cryptomator. Update cryptomator to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
