About Nimbletech Ezcast Pro Dongle Ii Firmware
CVE-2026-24346 affects Nimbletech Ezcast Pro Dongle Ii Firmware, a product from Nimbletech. Before acting, confirm where Nimbletech Ezcast Pro Dongle Ii Firmware runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: Use of well-known default credentials in Admin UI of EZCast Pro II version 1.17478.146 allows attackers to access protected areas in the web application
The weakness class is Hard Coded Credentials. A password or key is built into the software.
Based on its CVSS vector, the flaw needs local or adjacent access, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Nimbletech Ezcast Pro Dongle Ii Firmware and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Nimbletech Ezcast Pro Dongle Ii Firmware named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

A hard-coded cryptographic key is used by Altium Enterprise Server to sign file download URLs in the Vault service. Because the key is identical across all installations, an unauthenticated network attacker who can reach the server can forge valid download signatures and retrieve files from the Vault storage area without any authentication, session, or credentials. A separate path traversal vulnerability in the same download endpoint allows the configured storage root to be escaped, enabling reads of arbitrary files on the server filesystem. Combined, these issues allow an unauthenticated attacker to obtain sensitive server configuration and key material, which can lead to full server compromise. The vulnerability can be chained with CVE-2026-9152 to enumerate and bulk-download stored content. Altium 365 cloud deployments are not impacted in practice, as file storage uses object storage rather than the local filesystem.
Two undocumented privileged accounts exist in Autel Maxi Charger Single firmware through V1.03.51. The accounts use vendor-defined password derivation mechanisms based on device-specific values, allowing an attacker with knowledge of the algorithm and required inputs to authenticate to the web management interface with administrative privileges.
The upload.cgi binary, responsible for processing device backups, contains a hardcoded AES encryption key. This allows an attacker to decrypt, modify, and re-encrypt system backups, facilitating persistent backdoor injection.
Dell RecoverPoint for Virtual Machines, versions prior to 6.0.3.1 HF1, contain a hardcoded credential vulnerability. This is considered critical as an unauthenticated remote attacker with knowledge of the hardcoded credential could potentially exploit this vulnerability leading to unauthorized access to the underlying operating system and root-level persistence. Dell recommends that customers upgrade or apply one of the remediations as soon as possible.
Autel Maxi Charger Single firmware through V1.03.51 contains a hard-coded authentication token that bypasses authorization checks for multiple management endpoints. An attacker can supply the special token value to invoke privileged functionality without valid authentication.
FUXA v1.2.7 contains a hard-coded credential vulnerability in server/api/jwt-helper.js. The application uses a hard-coded secret key to sign and verify JWT Tokens. This allows remote attackers to forge valid admin tokens and bypass authentication to gain full administrative access.
