Shortpixel Image Optimizer
Monthly
Authenticated PHP Object Injection in the ShortPixel Image Optimizer WordPress plugin (versions 6.4.3 and earlier) allows attackers with Author-level privileges to trigger unsafe deserialization of attacker-controlled data, enabling code execution or other impacts when a suitable PHP gadget chain is present. Reported by Patchstack with no public exploit identified at time of analysis, the flaw is tracked as CWE-502 and carries a CVSS 3.1 score of 7.2 due to the high-privilege prerequisite but full CIA impact.
PHP object injection in the ShortPixel Image Optimizer WordPress plugin through version 6.5.5 allows an authenticated user with Subscriber-level access or higher to pass attacker-controlled data into an unsafe deserialization path, potentially achieving limited confidentiality and integrity impact inside the plugin's scope. Exploitation is conditional and high-complexity: it only yields meaningful escalation if a usable POP gadget chain exists in WordPress core, another installed plugin, or the active theme, and no public exploit identified at time of analysis. The main exposure is sites that permit open Subscriber registration, since the attacker must first hold a low-privileged account.
