CVE-2025-57964Network attack vector

Contributor-level stored script execution via unescaped content

Published Sep 22, 2025 · Updated Sep 22, 2025

Stored XSS in photonicgnostic Library Bookshelves 5.11 and earlier allows remote authenticated users to execute scripts in visitors' browsers. The plugin stores contributor-supplied content without sufficient sanitization and later renders it without adequate output escaping; public records do not identify the exact field or function. Contributor-level access is sufficient, and execution requires another user to open the injected page; no server-side code execution is reported.
