Impact and Attack Scenarios
The SSRF vulnerability in Sonaar MP3 Audio Player allows an attacker to craft malicious requests that appear to originate from the plugin itself. This can be exploited to scan internal networks for open ports and services, access sensitive data stored on internal servers (e.g., database credentials, API keys), or even modify data within internal systems. An attacker could potentially leverage this to gain a foothold within the internal network, leading to further compromise. The lack of authentication requirements for exploiting this vulnerability significantly broadens the potential attack surface, making it a high-priority concern for WordPress administrators.
Exploitation Context
CVE-2026-39647 was published on 2026-02-15. The vulnerability's SSRF nature makes it potentially attractive to attackers seeking to map internal networks. While no public exploits have been identified at the time of writing, the ease of exploitation and the plugin's popularity suggest a risk of active exploitation. The vulnerability is not currently listed on KEV or EPSS, indicating a low to medium probability of exploitation.
