IDM's kernel driver hands out SYSTEM, Orion Visor's hardcoded key leaks every credential

CVE-2026-90493 (CVSS 8.8) is a privilege escalation in Internet Download Manager's idmwfp.sys driver with a public exploit and no vendor response. CVE-2026-90510 (CVSS 8.3) exposes all stored host credentials in Orion Visor through a hardcoded encryption key. Plus unpatched SQLi in Feng Office and a certificate validation failure in Kalkitech ICS gear.

Nothing's on fire, but a couple of these deserve your attention before the weekend. Internet Download Manager's kernel driver has a privilege escalation bug (CVE-2026-90493, CVSS 8.8) with a public exploit and zero vendor response. Orion Visor is right behind it: a hardcoded crypto key that lets anyone decrypt stored host credentials (CVE-2026-90510, CVSS 8.3), also with a public exploit.

CVE-2026-90495

NVD
7.3
CVSS
Patch within 24h HIGH
Feng OfficeLinuxWindows

An attacker can inject SQL remotely through the Legacy API in Feng Office by manipulating the 'auth' parameter in the CompanyWebsite contacts lookup. This could let them read or modify your entire Feng Office database without authentication. A public exploit is available, and the vendor has not responded.

Affected estate
Teams running self-hosted Feng Office version 3.11.13.11 or earlier
How to check
Check your Feng Office version in the admin panel or in the source files. Confirm whether the Legacy API is exposed by reviewing your web server config for the relevant route.
Included because
unauthenticated; remote; SQL injection; public exploit available; vendor unresponsive
Action
Upgrade Feng Office if a fix is available. Otherwise, block or restrict access to the Legacy API at your reverse proxy or firewall.
Why it matters
Remote, unauthenticated SQL injection with a public exploit means your database is one HTTP request away from compromise.

CVSS
Patch this week HIGH
Kalkitech ASE2000IEC 60870 5 104WindowsNetwork Appliance

The IEC 60870-5-104 TLS client in the Kalkitech ASE2000 V2 Communication Test Set doesn't properly validate certificates. A network-positioned attacker can present a malformed certificate and intercept supposedly encrypted SCADA/ICS traffic via a Man-in-the-Middle attack. This only affects versions 2.35 through 2.37 and specifically the Task Mode TLS client.

Affected estate
ICS/SCADA engineers and utility operators using the Kalkitech ASE2000 V2 Communication Test Set versions 2.35 through 2.37 on Windows
How to check
Check the firmware version in the ASE2000 device interface or configuration utility.
Included because
ICS/SCADA equipment; TLS bypass; network-positioned MitM; CVSS 7.4
Action
Apply a firmware update from Kalkitech if one exists. Segment the device onto a trusted, isolated network to reduce MitM risk.
Why it matters
Broken TLS validation on an ICS test tool means an attacker on the network can silently intercept or tamper with SCADA protocol traffic.

CVE-2026-90510

NVD
8.3
CVSS
Patch within 24h HIGH
Dromara Orion VisorLinuxWindows

Orion Visor (by dromara) uses a hard-coded cryptographic key to encrypt host keys. Any attacker who reads the source code, which is publicly available, knows the key and can decrypt every stored host credential. This is remotely exploitable and a public exploit exists.

Affected estate
Anyone running self-hosted dromara Orion Visor version 2.5.7 or earlier for remote host management
How to check
Check your deployed Orion Visor version. Review the HostKeyServiceImpl class to confirm whether the hard-coded key is present in your build.
Included because
remote; hard-coded crypto key; credential exposure; public exploit; CVSS 8.3
Action
Upgrade Orion Visor to a version with a unique, configurable encryption key. After upgrading, rotate all stored host keys and credentials immediately.
Why it matters
A hard-coded key in an open-source project means every stored credential is effectively in plaintext to anyone who looks at the repo.

CVE-2026-90522

NVD
7.3
CVSS
Patch this week HIGH
Tourism Management SystemLinuxWindows

The password recovery function in Tourism-Management-System generates weak or predictable reset tokens. A remote attacker can exploit this to take over arbitrary user accounts without knowing the original password. A public exploit exists and a patch commit is available.

Affected estate
Developers or operators running the jaychouchannel Tourism-Management-System project
How to check
Check your deployed commit hash against the fix commit (9cb6215ac871f99a90cde763cf003e95ff282283). If your build is older, you're affected.
Included because
remote; account takeover via weak recovery; public exploit; CVSS 7.3
Action
Pull and deploy the patched commit. Invalidate all outstanding reset tokens and force password resets for accounts that recently used account recovery.
Why it matters
Weak password recovery lets a remote attacker hijack any user account, which could expose customer data and admin access.
