CVE-2026-3058: S-Sols Seraphinite Accelerator

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The Seraphinite Accelerator plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.28.14 via the `seraph_accel_api` AJAX action with `fn=GetData`. This is due to the `OnAdminApi_GetData()` function not performing any capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve sensitive operational data including cache status, scheduled task information, and external database state.

Affected products

• S-Sols Seraphinite Accelerator: before 2.28.15 (fixed in 2.28.15)
