- Published: 2022-02-28 · Updated: 2024-08-03

## Affected

- Unknown Post Snippets: from 3.1.4, fixed in 3.1.4

## Description

The Post Snippets WordPress plugin before 3.1.4 does not have CSRF check when importing files, allowing attacker to make a logged In admin import arbitrary snippets. Furthermore, imported snippers are not sanitised and escaped, which could lead to Stored Cross-Site Scripting issues
