Atomic Edge analysis of CVE-2025-14835 (metadata-based):
This vulnerability is a reflected cross-site scripting (XSS) flaw in the WP Photo Album Plus WordPress plugin. The vulnerability exists in all plugin versions up to and including 9.1.05.008. The ‘shortcode’ parameter lacks proper sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary JavaScript. The CVSS score of 7.1 (High) reflects a network-based attack requiring user interaction but leading to impacts across multiple security scopes.
Atomic Edge research infers the root cause is improper neutralization of user-supplied input before it is included in output HTML. The CWE-80 classification confirms this as a basic XSS flaw. The vulnerability description explicitly cites insufficient input sanitization and output escaping on the ‘shortcode’ parameter. Without access to source code, Atomic Edge cannot confirm the exact vulnerable function, but the pattern matches a common WordPress plugin failure where user input from GET or POST parameters echoes directly without using `esc_*` functions like `esc_html` or `esc_js`.
Exploitation requires an attacker to craft a malicious link containing a JavaScript payload within the ‘shortcode’ parameter. The victim must click this link while authenticated to WordPress. A likely attack vector involves a frontend page or AJAX handler that processes and outputs the shortcode parameter value. A realistic payload would be `alert(document.domain)` or a more malicious script to steal session cookies. The attacker could embed this payload in a phishing email or a compromised website.
Remediation requires proper output escaping or input sanitization. The patched version 9.1.05.009 likely added escaping functions such as `esc_html` or `esc_attr` around the echoed shortcode parameter value. Input validation might also have been implemented, but output escaping is the primary defense for reflected XSS in WordPress. Developers should follow the core WordPress coding standard to escape all dynamic data on output.
Successful exploitation allows an attacker to execute arbitrary JavaScript in the victim’s browser session. The impact includes session hijacking, content manipulation, and malicious redirects. The CVSS vector indicates impacts on confidentiality, integrity, and availability within the user’s browser context (Scope:Changed). An attacker could leverage this to perform actions as the victim user, potentially leading to site defacement or admin privilege escalation if a high-privileged user is targeted.
