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.
Today's CVEs
Sorted by urgencyCVE-2026-90493
NVDA local attacker can exploit broken access controls in Internet Download Manager's kernel driver (idmwfp.sys) to escalate privileges on Windows. Because this runs at the kernel level, a successful exploit could give full system control. A public exploit already exists, and the vendor has not responded to disclosure.
- Affected estate
- Windows users and admins running Internet Download Manager (IDM) version 6.42 Build 63 or earlier
- How to check
- Look for idmwfp.sys in your driver store or check IDM's Help > About for the build number. Software inventory tools can also flag the installed version.
- Included because
- kernel-level privilege escalation; public exploit available; CVSS 8.8; vendor unresponsive
- Action
- Update IDM if a newer build is available. If no patch exists, uninstall or disable IDM to remove the kernel driver from the attack surface.
- Why it matters
- A kernel driver bug with a public exploit means any local user or malware on the box can escalate to SYSTEM.

CVE-2026-90495
NVDAn 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.

CVE-2026-90647
NVDThe 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
NVDOrion 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
NVDThe 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.
