The vulnerability CVE-2021-24780 affects the WordPress plugin Single Post Exporter versions 1.1.1 and below. This security flaw was publicly disclosed on November 15, 2021, and was discovered by security researcher Francesco Carlucci. The vulnerability involves a Cross-Site Request Forgery (CSRF) issue in the plugin's settings management functionality (WPScan).

The vulnerability is classified as a Cross-Site Request Forgery (CSRF) with a CVSS score of 5.4 (medium severity) and is mapped to CWE-352. The technical issue stems from the plugin's lack of CSRF checks when saving its settings. Additionally, there is a secondary issue related to lack of authorization on the export feature. The vulnerability is categorized under OWASP Top 10 as A2: Broken Authentication and Session Management (WPScan).

The vulnerability allows attackers to modify plugin settings through a CSRF attack when targeting logged-in administrators. Once exploited, it can grant access to the export feature to any role, including subscribers. This means that even unauthorized users can potentially export arbitrary posts or pages, including private and password-protected content, via direct URL access (WPScan).

As of the last update on April 11, 2022, there is no known fix available for this vulnerability. Users of the Single Post Exporter plugin should consider implementing alternative solutions or removing the plugin until a security patch is released (WPScan).
