## Version 6

### v6.10.4

Released on Dec 11th, 2025

#### Minor Reflected SSRF fix

We have been reported (CVE incoming) that a minor SSRF vulnerability was still present in Lychee.
The patch from v6.6.13 did not fully mitigate the issue because an edge case had not been considered.
Validation is done on the initial URL; however, if the URL is redirected, the redirection target was not validated against local network etc.
To fix this, we added a new _expert_ configuration option in the admin section which disables following redirects when importing from URL.


A big thanks to TableBasse, midfirewear, and petouha for reporting this vulnerability to us.
