Summary
Versions of `swagger-ui` prior to 3.18.0 are vulnerable to [Reverse Tabnapping](https://www.owasp.org/index.php/Reverse_Tabnabbing). The package uses `target='_blank'` in anchor tags, allowing attackers to access `window.opener` for the original page. This is commonly used for phishing attacks.
## Recommendation
Upgrade to version 3.18.0 or later.
Patch / fix
- npm swagger-ui 3.18.0

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
