CVE-2025-5700: 
WordPress vulnerability analysis and mitigation

The Simple Logo Carousel plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability (CVE-2025-5700) discovered on June 17, 2025. The vulnerability affects all versions up to and including 1.9.3 and is caused by insufficient input sanitization and output escaping of the 'id' parameter. This security issue has been assigned a CVSS v3.1 base score of 6.4 (MEDIUM) (NVD Database, Wiz Report).

The vulnerability stems from improper neutralization of input during web page generation (CWE-79) in the plugin's functionality. The issue specifically relates to the 'id' parameter that lacks proper input sanitization and output escaping. The vulnerability has been assigned a CVSS v3.1 vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, indicating network accessibility with low attack complexity and requiring low privileges (NVD Database).

When exploited, this vulnerability allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses an injected page, potentially leading to session hijacking, credential theft, or other client-side attacks (Wiz Report).

A fix has been implemented in the plugin's codebase that properly sanitizes the 'id' parameter using WordPress's absint() function. Users should update to a version newer than 1.9.3 to protect against this vulnerability (Github Commit).
