Deeper analysis
CVE-2025-26580 is a Cross-Site Request Forgery (CSRF) vulnerability in the WordPress plugin Page/Post Specific Social Share Buttons, also referred to as Complete SEO Page/Post Specific Social Share Buttons, that enables Stored Cross-Site Scripting (XSS). Published on 2025-02-13, the issue affects all versions from n/a through 2.1 inclusive and is associated with CWE-352, with 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).
The vulnerability can be exploited by unauthenticated attackers over the network with low attack complexity, requiring user interaction such as an administrator visiting a malicious webpage. This triggers a CSRF request that injects a stored XSS payload into the plugin's configuration, which then executes in the browser context of subsequent users viewing affected pages, potentially leading to low-level impacts on confidentiality, integrity, and availability within a changed security scope.

Mitigating Controls (NIST 800-53 r5) AI
SC-23 enforces session authenticity mechanisms like anti-CSRF tokens, directly preventing unauthenticated attackers from forging requests to inject XSS payloads into the plugin configuration.
SI-10 requires validation of inputs to the plugin's configuration settings, blocking malicious XSS payloads from being stored even if a CSRF request succeeds.
SI-15 mandates filtering of outputs when rendering plugin configuration or share buttons, preventing execution of any stored XSS payloads in users' browsers.
