  Command Injection Local Privilege Escalation in Plesk for Linux
  CVE-2026-67394 is an OS command injection flaw (CWE-78) in Plesk for Linux that lets a low-privileged hosting tenant escalate to the root account on the hosting server. It is triggered by a customer or reseller who has shell access — or is allowed to change their own shell access setting — causing injected operating-system commands to run with elevated privileges; the CVSS network attack vector reflects that this can be done remotely by an authenticated tenant account. Successful exploitation yields full root control of the server, with high impact on confidentiality, integrity, and availability, and on the security of all sites hosted on that box. All Plesk for Linux installations running versions from 18.0.34 prior to 18.0.79.9 and prior to 18.0.80.5 are affected. No public proof-of-concept exists, the flaw is not in CISA's KEV catalog, and EPSS gives it a 1.3% chance of exploitation within 30 days, so no active exploitation is currently known.

  Authenticated Root RCE via Improper Symlink Handling in Plesk
  Plesk, the WebPros hosting control panel, resolves symlinks without verifying their targets before file access (CWE-59, link following), so privileged panel operations can be redirected through an attacker-controlled symlink. The flaw is triggered remotely by an authenticated low-privileged user — for example a tenant account on a shared hosting server — who gets Plesk's privileged file operations to follow a malicious link. A successful attacker executes arbitrary code with root privileges on the hosting server, compromising the control panel, every site it hosts, and the underlying OS. All Plesk deployments are potentially affected, but the specific vulnerable version range is not given in the available data, so operators should consult WebPros advisory AV26-854 for fixed releases. No public PoC, KEV listing, or confirmed in-the-wild exploitation is known, and EPSS estimates only about a 0.5% probability of exploitation within 30 days.

  Authenticated IDOR in WebPros Plesk exposes other customers' databases
  CVE-2026-65642 is an insecure direct object reference (IDOR, CWE-639) in Plesk, the WebPros hosting control panel, affecting versions 18.0.79.7 and earlier as well as 18.0.80 through 18.0.80.3. A remote user with a valid account on the server can reference a database identifier belonging to a different customer without an ownership check, because the application fails to verify that the requested object belongs to the requesting user. This lets the attacker read and modify other customers' databases on a shared Plesk server, giving high confidentiality and integrity impact but no availability impact (CVSS 4.0: 8.6 High). Exposure is concentrated in multi-tenant hosting environments, where hosting providers and agencies run one Plesk server for many customer accounts; single-tenant deployments have little to lose from this flaw. As of now there is no public proof of concept, the issue is not in CISA's KEV catalog, and EPSS estimates only a 0.5% probability of exploitation in the next 30 days, so exploitation has not been observed.
