CVE-2026-85017: CWE-502 Deserialization of Untrusted Data in Unlimited Elements For Elementor
The Unlimited Elements For Elementor WordPress plugin before 2.0.20 does not perform a capability check on an AJAX action and deserializes attacker-controlled stored data through it, which makes it possible for authenticated attackers with subscriber-level access to inject arbitrary PHP objects. A partial fix in the 2.0.18 to 2.0.19 releases raised the privilege required to reach the vulnerable action to editor-level, and the issue was fully resolved in 2.0.20.
AI Analysis
Technical Summary
CVE-2026-85017 is a deserialization of untrusted data vulnerability (CWE-502) in the Unlimited Elements For Elementor WordPress plugin. The plugin did not perform proper capability checks on an AJAX action, allowing authenticated attackers with subscriber-level access to inject arbitrary PHP objects by deserializing attacker-controlled stored data. This could lead to code injection or other impacts depending on the PHP object injection. The vulnerability was partially mitigated in versions 2.0.18 and 2.0.19 by increasing the privilege requirement to editor-level and fully fixed in version 2.0.20.
Potential Impact
Authenticated users with subscriber-level access could exploit this vulnerability to inject arbitrary PHP objects, potentially leading to code execution or other malicious actions within the WordPress environment. The partial fix limited exploitation to users with editor-level privileges, reducing the attack surface before the full fix in 2.0.20.
Mitigation Recommendations
Upgrade the Unlimited Elements For Elementor plugin to version 2.0.20 or later, where the vulnerability is fully resolved. Versions 2.0.18 and 2.0.19 include a partial fix by raising the required privilege level to editor, but upgrading to 2.0.20 is recommended for complete remediation.
