OpenWrt luci-app-dockerman (LuCI master and openwrt-25.12 snapshots containing the ucode docker_rpc.uc RPC backend after the JS/ucode conversion) contains an OS command injection vulnerability. The package's read ACL grants broad ubus access to docker.* / docker.container.*, which exposes the docker.container.ttyd_start method even though it performs mutating operations. The run_ttyd handler builds a shell command from the request-controlled id, cmd, and uid fields and passes it to system() without quoting or argv-style execution in the rpcd root context. An authenticated attacker holding only the luci-app-dockerman read ACL can inject shell metacharacters (e.g., in id) to execute arbitrary commands as root via an HTTP POST to /ubus. openwrt-24.10 and openwrt-23.05 do not contain this backend and are not affected; no patched version was known as of the advisory.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
