CVE-2023-6708SVG Support <= 2.5.7 - Authenticated (Author+) Cross-Site Scripting via SVG
Medium 5.4
In plain English
A medium-severity cross-site scripting in SVG Support from benbodhi. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 27% of all known vulnerabilities).
Official description
The SVG Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the SVG upload feature in all versions up to, and including, 2.5.7 due to insufficient input sanitization and output escaping, even when the 'Sanitize SVG while uploading' feature is enabled. 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 an injected page. Note that successful exploitation of this vulnerability requires the administrator to allow author-level users to upload SVG files. As of 2.5.6, SVG sanitization can still be bypassed by supplying a content-type other than image/svg+xml.
