Fluxbox through 1.3.7 contains an OS command injection vulnerability in RootTheme::reconfigTheme() that allows attackers to execute commands via crafted style background values. Attackers can embed shell metacharacters in background pixmap paths, random directories, or gradient texture text, which are concatenated unescaped into an fbsetbg command run via $SHELL -c when the style loads.

CVE-2026-330508.8 HIG—
——0GeoNode is a geospatial content management system, a platform for the management and publication of geospatial data. Prior to 5.1.0, a crafted vector file layer name supplied during upload allows a low-privileged remote user to inject shell syntax and execute arbitrary operating-system commands on the GeoNode server. This issue is fixed in version 5.1.0.1hCVE-2026-1233570.0 NO —
——0GROBID is machine learning software for extracting information from scholarly documents. Prior to 0.9.1, the Linux non-server PDF conversion path in grobid-core/src/main/java/org/grobid/core/document/DocumentSource.java passes an attacker-influenced PDF filename through DocumentSource.pdfalto, which interpolates the path into a bash -c command string. A single quote in the filename can terminate the intended quoting, and ProcessRunner.run in grobid-core/src/main/java/org/grobid/core/process/ProcessRunner.java starts the resulting command through ProcessBuilder, allowing arbitrary commands to execute with GROBID process privileges. The bundled REST server path is not affected. This issue is fixed in version 0.9.1.2hCVE-2026-1238557.5 HIG—

——0OS command injection in the example SSM document provisioning script in Trusted Remote Execution (REX) before 2026-07-28 might allow an authenticated remote user who is permitted to invoke the Rex-RO or Rex-RW SSM document to execute arbitrary commands as root on the managed instance, bypassing Cedar policy enforcement.
To remediate this issue, users should delete any Rex-RO and Rex-RW SSM documents created from the example script, in each account and Region where it was run.3hCVE-2026-1236207.5 HIG—
——0Usermin through 2.570 contains an OS command injection vulnerability in the Read Mail module that allows authenticated users to execute commands through unsanitized IMAP folder names. Attackers can create a folder containing shell metacharacters via an external IMAP client, then delete it in Usermin to run commands as their system account, bypassing webmail-only restrictions.6h
