CVE-2025-11812: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in redq Reuse Builder
The Reuse Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'reuse_builder_single_post_title' shortcode in all versions up to, and including, 1.7. This is due to insufficient input sanitization and output escaping on the 'style' attribute. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-11812 is a stored cross-site scripting vulnerability in the Reuse Builder WordPress plugin (versions up to 1.7). It occurs due to improper neutralization of input in the 'style' attribute processed by the 'reuse_builder_single_post_title' shortcode. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of users viewing the affected pages. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 base score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and scope change.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who visit the infected pages, potentially leading to information disclosure or manipulation of content within the affected site context. The impact is limited to confidentiality and integrity; availability is not affected. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access carefully and consider disabling or removing the Reuse Builder plugin if possible. Monitor for updates from the vendor or plugin maintainers and apply patches promptly once released.
