Technical description

FreePBX is an open source IP PBX. Prior to 16.0.6 and 17.0.5.4, the FreePBX Text-To-Speech module allows an authenticated administrator to save a TTS destination name that is HTML-encoded for storage, decoded during dialplan generation, passed as an AGI argument, and used to build filenames inside agi-bin/propolys-tts.agi. The TTS destination name reaches a raw shell-command execution path, allowing arbitrary operating-system command execution as the asterisk service user. This issue is fixed in versions 16.0.6 and 17.0.5.4.

———A vulnerability was identified in Baicells EG3661M BaiCE_BQ6_2.0.5.3_NA. This impacts an unknown function of the file /cgi-bin/luci of the component LuCI Web Interface. Such manipulation of the argument MaxHops/Timeout/Size leads to os command injection. The attack may be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.17h CVE-2026-736678.8 HIG

———OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.4, 1.1.4, and 1.2.0-rc.2, OpenChoreo Workflow Plane templates under samples/getting-started/workflow-templates/ interpolated developer-controlled workflow parameters into shell program text executed through sh -c instead of passing the values through container.env, allowing arbitrary commands to run in workflow pods while affected privileged Podman templates lacked hostUsers: false. This issue is fixed in versions 1.0.4, 1.1.4, and 1.2.0-rc.2.21h CVE-2026-73662—

———FreePBX is an open source IP PBX. From 17.0.1 until 17.0.7, the FreePBX Music on Hold module permits dangerous command-line options for /usr/bin/mpg123 and other allowed players in validateCustomConfiguration() in Music.class.php. An authenticated administrator can use options that write files, open control channels, or create Asterisk call files because applicationUsesDisallowedPlayerOption() does not reject those arguments, resulting in arbitrary command execution as the asterisk service user. This issue is fixed in version 17.0.7.21h CVE-2026-735708.9 HIG

———A remote code execution vulnerability exists in Zimbra Collaboration (ZCS) before 10.1.20 when the optional zimbra-snmp package is installed and SNMP notifications are enabled. Due to improper sanitization of untrusted input during SNMP notification processing, an unauthenticated attacker can send specially crafted SMTP requests that may result in execution of arbitrary operating system commands as the Zimbra user.14h CVE-2026-736258.8 HIG

——0GitPython versions before 3.1.54 contain a remote code execution vulnerability in the check_unsafe_options guard that can be bypassed by smuggling git options inside single-character kwarg values. Attackers can supply crafted option dictionaries to clone_from, fetch, pull, push, ls_remote, iter_commits, blame, or archive methods to execute arbitrary OS commands via the --upload-pack parameter.1d
