CVE-2024-10367: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in themeisle Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE
The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REST API SVG File uploads in all versions up to, and including, 3.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
AI Analysis
Technical Summary
The Otter Blocks plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, SVG files uploaded via the REST API are not properly sanitized or escaped, allowing authenticated users with Author-level privileges or higher to embed arbitrary scripts. These scripts execute when any user accesses the SVG file, potentially leading to cross-site scripting attacks. The vulnerability affects all versions up to 3.0.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required at the Author level, no user interaction, and impacts on confidentiality and integrity with no availability impact. There is no vendor advisory or patch information currently available, and the product is not a cloud service.
Potential Impact
An attacker with Author-level access or higher can exploit this vulnerability to inject and store malicious scripts within SVG files uploaded through the REST API. These scripts execute in the context of users who view the SVG files, potentially leading to unauthorized actions such as session hijacking or data theft. The impact affects confidentiality and integrity but does not affect availability. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Author-level access to trusted users only and consider disabling SVG file uploads via the REST API if possible. Monitor for updates from themeisle regarding patches or official mitigations.
