# CVE-2024-29833: WordPress Photo Gallery Plugin \<= 1.8.21 Stored Cross Site Scripting in UploadHandler

- Severity: CVSS 5.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2024-03-26 · Updated: 2024-08-02

## Affected

- 10Web PhotoGallery: from 1.0.1, through 1.8.21

## Description

The image upload component allows SVG files and the regular expression used to remove script tags can be bypassed by using a Cross Site Scripting payload which does not match the regular expression; one example of this is the inclusion of whitespace within the script tag. An attacker must target an authenticated user with permissions to access this feature, however once uploaded the payload is also accessible to unauthenticated users.

## What to do

- Check your stack: if you ship or depend on 10Web PhotoGallery, no fixed version is listed yet; follow the vendor advisory per the references below.
