sylius/sylius fixed: 1.8.3
Upgrade sylius/sylius to 1.8.3
sylius/sylius fixed: 1.6.9
Upgrade sylius/sylius to 1.6.9

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-15245, inspect your project dependencies for Sylius/sylius:

inspect dependencies for sylius/sylius

Analyze the terminal output to locate any version of Sylius/sylius in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.9), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Sylius/sylius, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The user may register in a shop by email mail@example.com, verify it, change it to the mail another@domain.com and stay verified and enabled. This may lead to having accounts addressed to totally different emails, that were verified. Note, that this way one is not able to take over any existing account (guest or normal one). ### Patches Patch has been provided for Sylius 1.6.x and newer - 1.6.9, 1.7.9, 1.8.3. Versions older than 1.6 are not covered by our security support anymore. ### Workarounds If for whatever reason you are not able to upgrade your application version, you may resolve this issue on your own by creating a custom event listener, which will listen to the `sylius.customer.pre_update` event. You can determine that email has been changed if customer email and user username are different. They are synchronized later on. Pay attention, to email changing behavior for administrators. You may need to skip this logic for them. In order to achieve this, you should either check master request path info, if it does not contain `/admin` prefix or adjust event triggered during customer update in the shop. You can find more information on how to customize the event here. ### Acknowledgements This security issue has been reported by Mircea Silviu (@decemvre), thanks a lot! ### For more information If you have any questions or comments about this advisory: * Email us at [security@sylius.com](mailto:security@sylius.com)
