No other products or prior versions are cited as vulnerable.", "description_and_impact": "The vulnerability allows a registered administrator to execute arbitrary system commands on the server running OpenProject. It stems from insufficient validation of the sendmail binary path that the application later uses when sending a test e\u2011mail. This introduces a command injection flaw (CWE\u201177) that can lead to full control over the installation, data, and network.", "risk_and_exploitability": "The CVSS score is 8.6, indicating high severity. The EPSS score is below 1\u202f%, pointing to a low but non\u2011zero probability of exploitation. The vulnerability is not listed in CISA\u2019s KEV catalog.
