Technical description

Hestia Control Panel is a lightweight and powerful control panel for the modern web. From version 1.9.7 through 1.10.4, update_object_value() in func/main.sh does not escape single quotes when writing a custom document-root value to a user's web.conf file, allowing a low-privileged authenticated panel user with a web domain to inject an additional PATH field. When the user invokes the ordinary Search feature, the root-privileged v-search-user-object script loads the forged field through parse_object_kv_list_non_eval(), which permits reserved shell-variable names and globally replaces PATH before invoking column without an absolute path. By placing a malicious column executable in the injected search path, the user can execute arbitrary code as root. This residual vulnerability was introduced when version 1.9.7 replaced the raw eval sink addressed by CVE-2026-84984 with parse_object_kv_list_non_eval(), and it is fixed in version 1.10.5.

——0GitPython before 3.2.0 contains an argument injection vulnerability in Head.checkout() that allows remote attackers to read arbitrary files by supplying a branch name parsed as a git option. Attackers can host a repository whose default branch is named --pathspec-from-file=<path>, causing cloning applications that check out the active branch to leak file contents through GitCommandError messages.8h CVE-2026-1108588.1 HIG

——0WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the pre-installation web/instalador/instalador.php endpoint is reachable before config.php exists and processes unauthenticated installation POST data. In the Linux reinstall flow, a crafted usuario value reaches a command executed by shell_exec(). The installer also writes attacker-controlled values into executable config.php and concatenates the database name nomebd into a CREATE DATABASE statement. Successful exploitation can execute commands as the web-server user, persist attacker-controlled PHP configuration, and alter or disrupt the application and its data. This issue is fixed in version 3.8.6.11h CVE-2026-54566—

——0Markdown Preview Enhanced is a Markdown preview extension for Visual Studio Code. Prior to 0.8.29, Markdown Preview Enhanced evaluates repository-controlled .crossnote/config.js and .crossnote/parser.js files with vm.runInNewContext, which does not provide a security boundary from the Node.js host realm. Opening a Markdown file in a malicious repository automatically loads these files, and prototype-chain traversal can reach the host Function constructor and process object, allowing operating-system commands to execute as the victim account without further interaction. Both configuration evaluation and parser-hook evaluation are affected, and the attack does not depend on module-scoped require being available. This issue is fixed in version 0.8.29.11h CVE-2026-857149.1 CRI

——0Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 2.13.2, an authenticated administrator using the default H2 database and security mode can upload a crafted SQL file to POST /api/v1/database/import-database. DatabaseService.validateSqlContent() splits normalized input on semicolons and accepts a statement when it contains any allowed keyword, allowing dangerous H2 functions such as FILE_READ and CSVWRITE, plus CREATE ALIAS, to bypass the insufficient whitelist and execute side effects when RUNSCRIPT processes the file. This permits arbitrary file access. The demonstrated operating-system command execution chain writes attacker-controlled startup files to a user-site location and then triggers an application Python interpreter configured to load those startup files, resulting in command execution as the JVM service account. This issue is fixed in version 2.13.2.12h CVE-2026-1081515.3 MED
