Severity Distribution
| Description | Vendor / Product | Exploit Status | |||
|---|---|---|---|---|---|
| CVE-2026-2460 | 7.6 | An attacker with low-level access can exploit a vulnerability in the REB500 firmware to change files and directories they shouldn't be able to modify. This requires the attacker to already have authenticated access to the system, making it a serious risk if such users are compromised. | hitachienergyreb500 firmware | Exploit Available | about 1 month agoFeb 24, 2026 |
| CVE-2026-2459 | 7.4 | This vulnerability allows an attacker with an Installer role to access and change files in directories they shouldn't be able to, potentially compromising the system's integrity.
