EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 55% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Donetick an open-source app for managing tasks and chores. Prior to version 0.1.44, the application uses JSON Web Tokens (JWT) for authentication, but the signing secret has a weak default value. While the responsibility is left to the system administrator to change it, this approach is inadequate. The vulnerability is proven by existence of the issue in the live version as well. This issue can result in full account takeover of any user. Version 0.1.44 contains a patch.
