An attacker can trick a site administrator into clicking a forged link to trigger a request that empties the entire subscriber list. The impact is a non\u2011authentication\u2011based data modification that removes all stored subscriber contacts, potentially disrupting marketing or communication channels and erasing leads that the site owner has accumulated.", "risk_and_exploitability": "The CVSS score of 4.3 indicates moderate severity, while the EPSS score of <1% suggests a very low probability of exploitation.

Exploitation requires a social\u2011engineering vector to convince an administrator to send the forged request; no direct code\u2011execution or remote\u2011code features are present.
