Technical description

ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.39.2, 1.38.2, and 1.36.40, ZoneMinder interpolates an unvalidated monitor Device field into shell commands in PHP and Perl control paths when an authenticated user with monitor-create or monitor-edit permission saves a Local monitor whose Device Path contains shell metacharacters and the monitor control or startup path runs. In this attack mechanism, the stored Device value reaches Perl qx() and backtick execution before zmdc.pl argument detainting, while separate PHP command paths use bypassable escapeshellcmd defenses. The attacker can execute arbitrary commands as the web server user. This vulnerability is fixed in 1.39.2, 1.38.2, and 1.36.40.

———Claude Agent SDK is a Python SDK for Claude Code. Prior to 0.2.121, the resume option is passed to the Claude CLI as a separate token without validation, so a dash-leading value is parsed as an independent CLI flag. An attacker can inject the --mcp-config flag to define a stdio MCP server, causing arbitrary command execution at CLI startup outside the SDK permission controls. The issue is exploitable when an application passes untrusted input as the session ID to resume. This issue is fixed in version 0.2.121.10h CVE-2026-108743—

———Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Apache Kylin. Impact most to the kylin services that are directly exposed to public network, which is not common. In-house kylin deployments are mostly not impacted. This issue affects Apache Kylin: from 4.0.4 through 5.0.4. Users are recommended to upgrade to version 5.0.5, which fixes the issue.9h CVE-2026-1026089.0 CRI

———ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.38.3, downloadEvents() manually wraps a monitor Name value in single quotes instead of using escapeshellarg() before placing it in shell commands when a user with monitor-create or monitor-edit permission stores a monitor Name containing shell metacharacters and a user with Events View permission exports that monitor's events. In this attack mechanism, the stored monitor Name reaches both the ffmpeg concatenation command and the tar or zip archive command and breaks out of manual quoting. Arbitrary commands execute as the web server user. This issue is fixed in version 1.38.3.10h CVE-2026-1026078.8 HIG

———ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.38.3, the exportEvents() function concatenates the attacker-controlled exportFile request parameter into a shell command without neutralizing shell metacharacters when an authenticated user with View Events or View Snapshots permission submits an event export request with a crafted exportFile value, a valid CSRF token, and exportDetail enabled. The affected components are exportEvents(), exportFile, web/ajax/event.php, web/skins/classic/includes/export_functions.php. In this attack mechanism, the crafted exportFile value reaches the trailing directory argument of a tar or zip command executed by exec(). The attacker can execute arbitrary operating system commands as the web server user. This issue is fixed in version 1.38.3.10h CVE-2026-922637.2 HIG

——0SparkyFitness is a self-hosted, AI-powered health and fitness tracker for families. Prior to 1.6.0, the api/admin/backup/restore endpoint interpolates an uploaded filename into a shell command. An authenticated global administrator uploads a restore archive with a crafted filename. The administrator can supply a restore archive with a filename containing shell metacharacters. Successful exploitation can execute arbitrary operating-system commands with the server process privileges. This issue is fixed in version 1.6.0.10h CVE-2026-887557.8 HIG
