CVE-2026-78392: Link Library < 7.9.6 - Contributor+ Stored XSS via 'link_target' Parameter
- Severity: medium (CVSS 6.8 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-10-22 · updated 2026-10-22
- Weakness: CWE-79
Description
The Link Library WordPress plugin before 7.9.6 does not sanitise and escape a link field before outputting it inside an attribute of a link preview, allowing users with the Contributor role and above to perform Stored Cross-Site Scripting attacks. The preview is generated without authentication and without checking whether the link has been published, so an unapproved submission is enough to reach any visitor who opens it.
Affected products
- Link Library: before 7.9.6 — fixed in 7.9.6
How to fix
Upgrade to a fixed version: Link Library 7.9.6. Check the vendor advisory for mitigations.
