# CVE-2023-2757: Waiting: One-click countdowns \<= 0.6.2 - Missing Authorization Checks leading to Authenticated (Subscriber+) Stored Cross-Site Scripting

- Severity: CVSS 7.4 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no

## Affected

- pluginbuilders Waiting: One-click countdowns: through 0.6.2

## Description

The Waiting: One-click countdowns plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on 'saveLang' functions in versions up to, and including, 0.6.2. This could lead to Cross-Site Scripting due to insufficient input sanitization and output escaping. This makes it possible for subscriber-level attackers to access functions to save plugin data that can potentially lead to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

## What to do

- Check your stack: if you ship or depend on pluginbuilders Waiting: One-click countdowns, no fixed version is listed yet; follow the vendor advisory per the references below.
