OPNsense before 26.7.8 contains a command injection vulnerability that allows authenticated users with the System: Firmware privilege to execute commands as root by storing a malicious firmware mirror URL. Attackers can submit shell metacharacters through POST /api/core/firmware/set that opnsense-update evaluates with eval, and can also disable package signature verification through sed injection.

CVE-2026-1197138.8 HIG—
———Paperclip 2026.403.0 before 2026.416.0 contains a remote code execution vulnerability that allows agent API key holders to set cleanupCommand and teardownCommand via PATCH /api/execution-workspaces/:id. When the workspace is archived, cleanupExecutionWorkspaceArtifacts runs these commands through a shell as the Paperclip server process, executing attacker-chosen OS commands on the server host.5hCVE-2026-1192887.0 HIG—
———Zuke is a code-first, strongly typed build automation system for Deno. Prior to 1.51.0, @zuke/core launches resolved Windows .cmd and .bat shims by prepending cmd /c, causing cmd.exe to reparse a command line assembled with C-runtime quoting rules. A build running on Windows that resolves a tool from node_modules/.bin and passes attacker-influenced text containing an unquoted &, |, or ^ metacharacter can execute an additional attacker-chosen command in the build's context with access to its credentials. POSIX platforms are not affected. This issue is fixed in version 1.51.0.4hCVE-2026-1182387.2 HIG—
———The Tenda W18E web management server is vulnerable to OS command injection via the "diagnose" packet-capture feature due to improper validation of JSON fields. An authenticated user can inject shell metacharacters into the protocol or targetDevice fields, which are later concatenated into a tcpdump command and executed with root privileges. This vulnerability can be exploited without authentication if the device is in a factory-reset state.4hCVE-2026-919138.8 HIG—
———Dell OpenManage Enterprise, versions prior to 4.8.0, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Command execution.4hCVE-2026-118992——
———CallBackery versions before 0.62.0 for Perl allow OS command execution via sqlite3 shell commands in a restored configuration backup.
restoreConfigBlob() feeds the database dump in a backup to the sqlite3 command-line shell. The shell runs lines starting with a dot as its own commands, so .shell or .system in the dump runs an OS command and .load loads native code.
Anyone who can supply a backup to be restored can run arbitrary commands as the application user.4hCVE-2026-1115058.8 HIG—
