### link-preview-js vulnerable to IPv6 and internal loopback attacks
[CVE-2026-43897](https://nvd.nist.gov/vuln/detail/CVE-2026-43897) /
[GHSA-4gp8-rjrq-ch6q](https://redirect.github.com/advisories/GHSA-4gp8-rjrq-ch6q)

<details>
<summary>More information</summary>

#### Details
##### Impact
The library did not check for IPv6 loopback attacks. There was also a
DNS attack, where an address could be resolved into an internal IP. This
could cause internal data leaks.

##### Patches
Problem has been patched in version 4.0.1. However, it cannot be
completely solved by the package alone. The regex used for validation
has been tightened for IPv6 addresses.

The DNS resolving, however, is more difficult. The regex has been
tightened to prohibit .internal, .local, .nip.io and .sslip.io
addresses, however there can be other services not on the list,
therefore it is imperative that users use the resolveDNSHost option to
do DNS resolution before fetching content. To that regard a (scary)
error message has been added when the option is not set.

##### Workarounds
Users can do their own validation before fetching content.
