Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Requires session authenticity mechanisms like CSRF tokens to prevent unauthenticated attackers from tricking authenticated users into submitting malicious requests.

prevent

Enforces validation of plugin inputs to block malicious payloads from being stored via CSRF exploitation, directly addressing the Stored XSS outcome.

prevent

Filters information outputs to prevent execution of any stored malicious scripts injected through the CSRF vulnerability in subsequent user sessions.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1204.001 Malicious Link Execution
An adversary may rely upon a user clicking a malicious link in order to gain execution.
Why these techniques?

CSRF vulnerability in public-facing WordPress plugin enables exploitation of the web application (T1190) and requires tricking users via malicious links to submit requests (T1204.001), leading to stored XSS.

Deeper analysisAI

CVE-2025-26550 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the WordPress plugin Global Meta Keyword & Description developed by Kunal Shivale. The flaw enables Stored Cross-Site Scripting (XSS) and affects all versions of the plugin up to and including 2.3. It 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 with low attack complexity, no required privileges, user interaction, and scope change resulting in low impacts to confidentiality, integrity, and availability.

Unauthenticated attackers (PR:N) can exploit this vulnerability by tricking authenticated WordPress users, such as administrators, into submitting malicious CSRF requests. Successful exploitation leads to Stored XSS, where malicious scripts are persistently injected and executed in the context of the site for subsequent visitors or admins, potentially enabling session hijacking, data theft, or further site compromise depending on the payload.

The primary advisory from Patchstack documents this CSRF-to-XSS issue specifically in plugin version 2.3 and is available at https://patchstack.com/database/Wordpress/Plugin/global-meta-keyword-and-description/vulnerability/wordpress-global-meta-keyword-description-plugin-2-3-csrf-to-cross-site-scripting-vulnerability?_s_id=cve. Security practitioners should consult this reference for detailed mitigation steps, which may include plugin updates if available or temporary workarounds like CSRF token enforcement.
