Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Bitlyshortener, 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 Due to a sudden upstream breaking change by Bitly, versions of `bitlyshortener` <0.5.0 can generate an invalid short URL when a vanity domain exists. ### Patches Upgrading `bitlyshortener` to 0.5.0 or newer will prevent the generation of any such invalid short URLs. ### References * [Release notes](https://github.com/impredicative/bitlyshortener/releases)
