# CVE-2026-44212: PrestaShop has a stored XSS executable in customer service view

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.4% , percentile 35: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 35% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes prestashop/prestashop (Composer (PHP)) < 8.2.6, fixed in 8.2.6 ; prestashop/prestashop (Composer (PHP)) >= 9.0.0, < 9.1.1, fixed in 9.1.1 . Check your lockfile, including transitive dependencies.

## What it is

PrestaShop is an open source e-commerce web application. Prior to 8.2.6 and 9.1.1, there is a stored Cross-Site Scripting (XSS) vulnerability in the PrestaShop back-office Customer Service view. An unauthenticated attacker can submit the public Contact Us form with a malicious email address. The payload is stored in the database and executed when a back-office employee opens the affected customer thread, enabling session hijacking and full back-office takeover. This vulnerability is fixed in 8.2.6 and 9.1.1.

## Affected packages

- Composer (PHP) `prestashop/prestashop` < 8.2.6 → fixed: 8.2.6
- Composer (PHP) `prestashop/prestashop` >= 9.0.0, < 9.1.1 → fixed: 9.1.1

## Affected products (CVE record)

- PrestaShop PrestaShop: < 8.2.6, >= 9.0.0-alpha.1, < 9.1.1

## Severity

- GitHub_M CVSS 3.1: 9.3 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N`
- GitHub CVSS 3.1: 9.3 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.42% probability of exploitation activity in the next 30 days; percentile 35.
