CVE-2025-62733 identifies a Cross-Site Request Forgery (CSRF) vulnerability within the Custom Sidebars plugin developed by ProteusThemes for WordPress. This flaw allows an attacker to potentially execute unauthorized actions on a user's account if they are tricked into clicking a malicious link. The vulnerability impacts versions 1.0.0 through 1.0.3 of the plugin, and a fix is available in a later version.
A successful CSRF attack could allow an attacker to modify sidebar configurations, potentially injecting malicious code or redirecting users to phishing sites. The impact is primarily related to the integrity of the WordPress site and the trust of its users. While the plugin itself might not contain sensitive data, modifications made through a CSRF attack could lead to further compromise of the website. The blast radius is limited to users interacting with the affected sidebar functionality.
This vulnerability was publicly disclosed on 2025-12-09. No public proof-of-concept (POC) code has been identified at the time of writing. The vulnerability is not currently listed on the CISA KEV catalog. The probability of exploitation is considered low to medium, pending the release of readily available exploit tools.
WordPress sites utilizing the Custom Sidebars plugin, particularly those with user roles that have administrative privileges over sidebar configurations, are at risk. Shared hosting environments where multiple websites share the same server resources could also be affected if one site is running a vulnerable version of the plugin.

The primary mitigation is to upgrade the Custom Sidebars plugin to a version that addresses this vulnerability. If upgrading is not immediately feasible, consider implementing strict input validation and output encoding on any user-supplied data used in sidebar configurations. Additionally, implement a CSRF protection mechanism, such as using nonce tokens for all critical actions within the plugin. After upgrading, verify the fix by attempting to trigger a sidebar modification through a crafted URL and confirming that the action is blocked.
