## How to fix

- Fixed in 4.4.18

## Technical details

The recuperer_url() function in ecrire/inc/distant.php follows up to 10 HTTP redirects without re-validating that the target URL is safe, only validating the initial URL with valider_url_distante(). Authenticated attackers can supply a remote URL (such as a syndicated feed or remote document) that redirects to internal, link-local, or cloud metadata addresses. The fix validates remote URLs at each redirect step.
