CVE-2026-1889 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the Outgrow WordPress plugin, affecting all versions up to 2.1. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious web scripts via the 'id' attribute of the 'outgrow' shortcode due to insufficient input sanitization. Rated as Medium severity (CVSS 6.4), exploitation requires low privileges and complexity, potentially leading to low impact on confidentiality and integrity as arbitrary scripts execute in a user's browser. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, with its EPSS score indicating a very low probability of future exploitation.
