dockhand: Authentication Bypass Using an Alternate Path or Channel
CVE-2026-110130 is a critical-severity authentication bypass using an alternate path or channel vulnerability in dockhand from Finsys, with a CVSS 3.1 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.0.45 as the first without the flaw, so updating dockhand to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.72% chance of exploitation within 30 days, higher than 54% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update dockhand to 1.0.45 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Dockhand before 1.0.45 contains an authentication bypass in which the global auth hook skips authentication for any path ending in a static-asset extension such as .js, including /api/* routes, and the user-mutation handlers fail open for unauthenticated callers. Unauthenticated remote attackers can send a PUT request to /api/users/<id>.js to reset the admin's or any user's password and take over the account.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
How developers prevent this class of flaw
- Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
