CVE-2025-23997Network attack vector

Stored script execution via unsanitized content

Published Jan 21, 2025 · Updated May 12, 2026

Stored XSS in Tamara Checkout before 1.9.9.1 allows remote authenticated users to inject scripts through WordPress content. Public records attribute the flaw to insufficient input sanitization and output escaping but do not identify the endpoint, parameter, or function. Contributor-level access is sufficient, and the script runs in the affected site's origin when a user views the injected page.
