SharedLicense lisansı altında bunun anlamı
Your SharedLicense license itself is not affected — this is a vulnerability in Plesk software, not in licensing. Licenses continue to work during and after the update; there is no need to re-issue or re-activate anything. If you resell Plesk under your own brand, patch client servers too — unpatched installs put your reputation at risk, not your license.
A Time-of-check Time-of-use (TOCTOU) race condition leading to insecure symlink following in Plesk causes local privilege escalation to root via arbitrary file/directory ownership takeover.
