Boost WordPress Plugin Injection Vulnerabilities

PHP Object Injection in the Boost plugin for WordPress (versions up to and including 2.0.3) allows unauthenticated remote attackers to inject arbitrary PHP objects via the STYXKEY-BOOST_USER_LOCATION cookie. The vulnerability stems from unsafe deserialization of attacker-controlled cookie data; while the plugin itself ships no usable POP (property-oriented programming) chain, exploitation becomes high-impact when any other installed plugin or theme provides one. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.

Unauthenticated SQL injection in the PixelYourSite Boost plugin for WordPress (versions up to and including 2.0.3) allows remote attackers to extract sensitive database contents via time-based blind SQLi in the 'current_url' and 'user_name' parameters. Wordfence reported the issue with a CVSS 7.5 (confidentiality-only impact); no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
