CVE-2026-70375: CWE-78 OS Command Injection in HashBrownCMS hashbrown-cms
HashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the Git deployer component. GitDeployer.pullRepo in src/Server/Entity/Deployer/GitDeployer.js executes AppService.exec, interpolating the configured branch value directly into a shell command with no escaping.
AI Analysis
Technical Summary
CVE-2026-70375 is an OS Command Injection vulnerability (CWE-78) in HashBrown CMS through version 1.4.6. The flaw exists in the Git deployer component, specifically in the GitDeployer.pullRepo function located in src/Server/Entity/Deployer/GitDeployer.js. This function calls AppService.exec with a shell command that includes the configured branch value directly, without escaping or sanitization, enabling command injection. The vulnerability allows an attacker with limited privileges to execute arbitrary commands on the host system, potentially leading to full system compromise.
Potential Impact
Successful exploitation allows an attacker with limited privileges to execute arbitrary operating system commands on the server running HashBrown CMS. This can lead to complete compromise of the system, including unauthorized disclosure, modification, or destruction of data, and disruption of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using untrusted input for the branch configuration in the Git deployer component. Restrict access to the affected functionality to trusted users only and consider applying additional OS-level restrictions to limit potential damage.
