CVE-2026-78397: CWE-918 Server-Side Request Forgery (SSRF) in Link Library
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.
AI Analysis
Technical Summary
The Link Library WordPress plugin before version 7.9.6 contains an SSRF vulnerability (CWE-918) where user-supplied URLs are not validated correctly. When the plugin's safe request mechanism is rejected, it falls back to an unprotected fetch, enabling unauthenticated attackers to make the server send requests to internal network hosts and infer the presence of internal services based on responses. Versions from 7.8.8 up to but not including 7.9.6 are affected. Versions prior to 7.8.8 are covered by a different CVE (CVE-2025-68600). Exploitation requires that the site owner has published the vulnerable plugin's public link submission form with reciprocal-link validation enabled.
Potential Impact
An unauthenticated attacker can leverage this SSRF vulnerability to make the vulnerable WordPress site send requests to internal network hosts. This can allow the attacker to discover internal services by analyzing responses, potentially aiding in further attacks or reconnaissance. The vulnerability does not allow direct code execution or data modification but can disclose internal network information.
Mitigation Recommendations
A fix is available in Link Library version 7.9.6. Site owners should upgrade to version 7.9.6 or later to remediate this vulnerability. Until upgraded, disabling the public link submission form with reciprocal-link validation or restricting access to it may reduce exposure. Patch status is confirmed by the version range affected and the fixed version 7.9.6.
