This flaw resides within the \u003ccode\u003ewpzoom_load_more_items\u003c/code\u003e AJAX action, which is accessible to unauthenticated users without proper nonce validation or privilege checks. Attackers can exploit this by crafting a malicious POST request that injects arbitrary JavaScript into the \u003ccode\u003eposts_data\u003c/code\u003e parameter's \u003ccode\u003eclass\u003c/code\u003e key. Although \u003ccode\u003esanitize_text_field()\u003c/code\u003e strips angle brackets, it fails to sanitize single quotes, allowing an attacker to break out of HTML attribute contexts and inject event handlers like \u003ccode\u003eonmouseover\u003c/code\u003e. The presence of a working Proof of Concept (PoC) significantly increases the immediate risk to organizations using vulnerable versions of this plugin.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker crafts a malicious HTTP POST request.\u003c/li\u003e\n\u003cli\u003eThe request targets the \u003ccode\u003e/wp-admin/admin-ajax.php\u003c/code\u003e endpoint on the vulnerable WordPress site.\u003c/li\u003e\n\u003cli\u003eThe POST request body includes \u003ccode\u003eaction=wpzoom_load_more_items\u003c/code\u003e and a \u003ccode\u003eposts_data\u003c/code\u003e parameter containing the XSS payload: \u003ccode\u003e{\u0026quot;source\u0026quot;:\u0026quot;post\u0026quot;,\u0026quot;class\u0026quot;:\u0026quot;x' onmouseover='alert(document.domain)' y='\u0026quot;}\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe server processes the \u003ccode\u003ewpzoom_load_more_items\u003c/code\u003e AJAX action; \u003ccode\u003esanitize_text_field()\u003c/code\u003e is applied to \u003ccode\u003eposts_data\u003c/code\u003e, stripping angle brackets but preserving single quotes.\u003c/li\u003e\n\u003cli\u003eThe attacker-controlled \u003ccode\u003eclass\u003c/code\u003e value is subsequently concatenated directly into single-quoted HTML attributes within the \u003ccode\u003eitems_html()\u003c/code\u003e function without context-aware output escaping (e.g., \u003ccode\u003e\u0026lt;li class='{$class}_item ...'\u0026gt;\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThe server's response includes the crafted HTML, such as \u003ccode\u003e\u0026lt;li class='x' onmouseover='alert(document.domain)' y='_item ...'\u0026gt;\u003c/code\u003e, which is then rendered in a victim's browser.\u003c/li\u003e\n\u003cli\u003eWhen a victim's browser renders the affected page and the victim interacts with the vulnerable element (e.g., hovering over the loaded portfolio item), the injected \u003ccode\u003eonmouseover\u003c/code\u003e JavaScript event handler executes.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves client-side script execution, potentially leading to session hijacking, defacement, or redirection to malicious sites.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eThe successful exploitation of CVE-2026-49069 can lead to various client-side attacks, including session hijacking, defacement of the affected WordPress site, redirection of users to malicious websites, or the delivery of further malware.
