medium Tenable Cloud Security Plugin ID 444044

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From
version 2.0.14 to before version 2.1.0, PATCH /server/{id} accepts and persists nonexistent ddns_profiles
IDs for a member-owned server. If another user later creates a DDNS profile with one of those IDs, the
DDNS worker resolves the stored ID and dispatches an update using the other user's DDNS profile
configuration in the context of the attacker's server. This issue has been patched in version 2.1.0.
(CVE-2026-53521)

Solution

Update the github.com/nezhahq/nezha library and its related packages to version 2.1.0 or later.
