CVE-2023-5087Public exploitNetwork attack vector

Stored script execution via unsanitized code fields

Published Oct 16, 2023 · Updated Apr 23, 2025

Stored cross-site scripting in Softaculous Pagelayer before 1.7.8 allows remote authenticated users to inject scripts into posts. The header, body, and footer code fields accept a closing textarea tag followed by JavaScript without sufficient sanitization or output escaping. Author-level access is required, and the stored script runs when another user views or previews the affected post, exposing that user's browser session to script actions.
