This allows the attacker to force the platform to rebroadcast a victim playlist under the victim\u2019s identity. The result is unauthorized content distribution or intentional disruption of the victim\u2019s stream, leading to loss of control over broadcast content.", "risk_and_exploitability": "The CVSS score of 6.3 indicates moderate severity. While no EPSS score is provided and the flaw is not listed in the KEV catalog, the vulnerability requires only an authenticated user with streaming permissions. An attacker can craft a schedule for another user\u2019s playlist, which executes automatically when the time triggers, allowing hijacking with no additional privilege escalation. Because the attack vector is internal to the platform, it is likely to be exploited by insiders or threat actors who have already compromised an account with streaming rights."}}}}, "created": "2026-03-27T20:28:03.079850+00:00", "updated": "2026-03-27T20:28:03.079898+00:00", "vendors": []}
