CVE-2026-3534 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Astra theme for WordPress, specifically versions up to and including 4.12.3. This medium-severity flaw (CVSS 6.4) stems from insufficient input sanitization and missing output escaping in background meta fields. It allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. These scripts execute when a user accesses an injected page, potentially leading to low confidentiality and integrity impacts like data theft or content manipulation. There is currently no evidence of active exploitation, public exploit code, or significant community attention for this vulnerability.
