# ShortPixel Adaptive Images WordPress plugin: stored XSS through version 3.11.6

Link for people: https://infrastack.ai/live/CVE-2026-125765 (this .md is for agents)

ShortPixel Adaptive Images up to 3.11.6 for WordPress does not properly escape image and background-image URLs it rewrites into CDN addresses and placeholder attributes. A logged-in user with Contributor access or higher (per WPSec) can store a script that runs for anyone who opens the affected page, administrators included. WPSec lists 3.12.0 as the fix.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- wordpress:shortpixel-adaptive-images affected <= 3.11.6 fixed 3.12.0

## How to check

- In WordPress admin > Plugins, or run: wp plugin get shortpixel-adaptive-images --field=version
- Versions <= 3.11.6 are affected; 3.12.0 is the fixed release per WPSec
- If you cannot update right away, review which users have Contributor or higher roles, and check recent posts for image or background-image URLs containing quotes or angle brackets

## Fix

Update ShortPixel Adaptive Images to 3.12.0 or later (per WPSec; WordPress.org shows a 3.12.0 release, but the plugin's own changelog line for this fix was not read).

## Timeline

- 2026-11-15T15:36:07+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-125765
- 2026-11-15T15:38:11+00:00 analyst https://wpsec.com/vuln/WPSEC-2026-3103/ — NVD (Patchstack-assigned) gives no fix or privilege. WPSec (third-party) says Contributor+ stored XSS via image/background-image URLs, fixed in 3.12.0 (released 2026-11-12). WordPress.org SVN has a 3.12.0 tag with stable tag 3.12.0, but I did not see a changelog line tying it to this CVE. Nothing marked verified. No exploitation or PoC found; I did not search X.
