CVE-2026-78397

Link Library < 7.9.6 - Unauthenticated SSRF via Reciprocal Link Validation

Published Sep 25, 2026 CVSS 3.1 · 4.0 Medium EPSS < 1% KEV · Not listed
Description
The Link Library WordPress plugin before 7.9.6 does not validate the destination of a user-supplied URL before falling back to an unprotected fetch when its safe request is rejected, allowing unauthenticated visitors to make the site issue requests to hosts on its internal network and to learn from the response whether an internal service answered.

Versions below 7.8.8 are covered by CVE-2025-68600; this entry covers 7.8.8 through 7.9.5, where that fix was incomplete. Exploitation requires the site owner to have published the Link Library WordPress plugin before 7.9.6's public link submission form with reciprocal-link validation enabled.
