Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-862.

Summary

The Link Library WordPress plugin before 7.10.0 does not re-check the login requirement of the selected library when it processes a front-end link submission. Unauthenticated users can submit links to a library that requires login by reusing a form token obtained from another library that does not require it, which is a missing authorization check (CWE-862). An unauthenticated remote attacker can add links to the protected library with low complexity and no user interaction. A public exploit is linked in the references, but the flaw is not listed in CISA KEV.

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.
