An attacker who gains the ability to execute arbitrary code on a system with TrueConf Server (Linux) versions from 4.7.2 up to, but not including, 5.5.6 installed, running as the user trueconf (by exploiting some other vulnerability), can elevate their privileges to root.

CVE-2026-1267858.8 HIG—
———A vulnerability has been found in rmalright TR-VISION HOME 2.0.5. Impacted is the function sub_11504 in the library WFanManager.sys of the component IOCTL Handler. Such manipulation leads to incorrect default permissions. The attack must be carried out locally. The vendor was contacted early about this disclosure but did not respond in any way.7hCVE-2026-890617.8 HIG—
———During an internal security assessment, a potential vulnerability was discovered in Lenovo PC Manager, distributed exclusively in the Chinese market, that could allow a local user to escalate privileges.15hCVE-2026-778737.3 HIG—
———An improper permissions vulnerability was reported in Lenovo System Update that could allow a local authenticated user to execute code with elevated privileges.15hCVE-2026-1266256.7 MED1.4%
——0Incorrect default permissions in the Windows installer of Progressive Robot hMailServer 6.3.7 allow a local authenticated user to run code as the administrator who installs the product, when it is installed into a new program folder in a location whose permissions let every user write, such as the root of a drive. 6.3.7 fixed CVE-2026-107571 by giving the program folder, Bin and ControlPanel permissions that only administrators may change, but its setup lets Inno Setup make a new program folder first, with the permissions the folder above hands down, and replaces them only afterwards, tens of milliseconds later (33 to 139 milliseconds in the project's test runs). In that time any local account may make files and folders in the new folder, which keep that account as their owner, among them the Bin folder that setup then copies the programs into. Setup runs programs from Bin with the administrator's elevated rights, registering the service among them, before its hardening at the end of setup takes such a folder back, and those programs load a library placed in Bin in place of the system's. The default installation under Program Files, whose folders give ordinary users read and execute only, is not affected.23hCVE-2026-1266227.3 HIG2.3%
——1Incorrect default permissions in the Windows installer of Progressive Robot hMailServer 6.3.7 allow a local authenticated user to run code as the administrator who runs setup, when the server is installed into a program folder that is already there and that accounts other than the administrators could write, such as a folder made beforehand at the root of a drive, or when such an installation is upgraded or repaired. 6.3.7 fixed CVE-2026-107571 by giving the program folder, Bin and ControlPanel permissions that only administrators may change, but for a folder that is already there it does so only at the end of setup: setup first copies the programs into Bin, which every user may still write, and runs programs from Bin with the administrator's elevated rights, registering the service among them, before that hardening, so that a library another account places in Bin meanwhile is loaded in place of the system's. A handle an account opened on such a folder while it could write it keeps that access after the hardening. The default installation under Program Files, whose folders give ordinary users read and execute only, is not affected.23hCVE-2026-1248485.5 MED1.2%
——0Incorrect default file permissions in Kiro CLI (formerly Amazon Q Developer CLI) before version 2.27.0 on macOS and Linux might allow other local users on the same host to read a user's session transcripts and prompt history, including any credentials or source code they contain. The CLI created its local session storage files with permissions that made them readable by all local users.
To remediate this issue, users should upgrade to Kiro CLI version 2.27.0 or later and launch it once. Users who ran Amazon Q Developer CLI 1.16.0 through 1.19.x should also delete the ~/.aws/amazonq/.cli_bash_history file or restrict it to the owner.1d
