By manipulating the query parameter topic, an attacker can craft a request that causes the application to construct a filesystem path containing directory traversal sequences such as ../.

The vulnerability can be triggered remotely and the exploit code is publicly available.", "risk_and_exploitability": "The CVSS score of 6.9 indicates a medium severity risk. Because the EPSS score is not provided, the exact likelihood of exploitation is unclear, but the vulnerability is listed as not in the CISA KEV catalog.
