Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Filters information prior to output on web pages to neutralize malicious scripts, directly preventing reflected XSS exploitation in the WordPress plugin.

prevent

Validates inputs at system entry points to reject or sanitize malicious payloads before they are reflected in web page generation.

prevent

Ensures timely identification, reporting, and correction of flaws like this reflected XSS vulnerability through patching the affected WP Social Broadcast plugin.

MITRE ATT&CK Enterprise TechniquesAI

T1566.002 Spearphishing Link Initial Access
Adversaries may send spearphishing emails with a malicious link in an attempt to gain access to victim systems.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

Reflected XSS in the plugin enables exploitation via crafted malicious links (T1566.002 Spearphishing Link) and allows injected JavaScript to steal web session cookies or session data (T1539 Steal Web Session Cookie).

Deeper analysisAI

CVE-2025-23545 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-site Scripting (XSS) as classified under CWE-79. It affects the WP Social Broadcast WordPress plugin (wp-social-broadcast) developed by Navnish Bhardwaj, impacting all versions from n/a through 1.0.0 inclusive. The vulnerability was published on 2025-01-23.

The issue carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network accessibility, low attack complexity, no privileges required, and user interaction needed for exploitation. Remote attackers can craft malicious payloads delivered via reflected inputs, tricking users into interacting (e.g., via a phishing link). Successful exploitation allows limited impacts on confidentiality, integrity, and availability within a changed scope, such as executing scripts in the victim's browser to steal session data or perform other client-side actions.
