CVE-2026-116537

Link Library <= 7.10.0 - Unauthenticated Stored Cross-Site Scripting via 'link_description' Parameter

The Link Library plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link_description' parameter in all versions up to, and including, 7.10.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This exploit requires the site administrator to have enabled the non-default 'Convert [] to <> in Link Description and Notes' (use_html_tags) setting; when this option is off, the bracket-to-angle-bracket conversion never runs and the payload is never reconstructed into executable HTML.

Link Library < 7.10.0 - Unauthenticated Link Submission Login Requirement Bypass

The Link Library WordPress plugin before 7.10.0 does not re-check the selected library's own login requirement when processing its front-end link submission, allowing unauthenticated users to submit links to a library configured to require login by reusing a form token obtained from another library that does not.

Link Library < 7.10.0 - Unauthenticated Link Contact and Submitter Information Disclosure

The Link Library WordPress plugin before 7.10.0 does not verify that a requested link belongs to the settings set whose display template is used to render it, allowing unauthenticated users to disclose the telephone number, e-mail address and submitter name stored with links that the settings set is configured not to display.

Link Library <= 7.9.2 - Unauthenticated SQL Injection via 'link_url' Parameter

The Link Library plugin for WordPress is vulnerable to time-based SQL Injection via the 'link_url' parameter in all versions up to, and including, 7.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Link Library < 7.9.6 - Contributor+ Stored XSS via 'link_target' Parameter

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.

CVE-2026-78397

Link Library < 7.9.6 - Unauthenticated SSRF via Reciprocal Link Validation

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.

Link Library < 7.9.6 - Reflected XSS via 'link_tags' and 'link_price' Sort and Breadcrumb Links

The Link Library WordPress plugin before 7.9.6 does not properly escape some parameters before outputting them in the addresses of links it generates on its front-end directory pages, leading to Reflected Cross-Site Scripting which could be used against any visitor, including logged-in administrators.

Link Library < 7.9.6 - Contributor+ Path Traversal via 'filepath' Parameter

The Link Library WordPress plugin before 7.9.6 does not sanitize a user-supplied destination folder before writing a generated image to disk, allowing users with the Contributor role and above to create directories and write or overwrite image files anywhere the web server can write, including outside the site's document root. The written file name is always numeric with a fixed image extension, so executable code cannot be planted this way.
