CVE-2026-1667

HIGH

SEO Plugin by Squirrly SEO <= 14.0.0 - Unauthenticated Arbitrary Post Creation and Stored Cross-Site Scripting via savePost()

Title source: cna
STIX 2.1

Description

The SEO Plugin by Squirrly SEO plugin for WordPress is vulnerable to Arbitrary Post Creation and Stored Cross-Site Scripting in all versions up to, and including, 14.0.0 due to a leak of an API token and insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to create arbitrary posts, and, if the Advanced Custom Fields plugin is installed and activated, inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
