CVE-2022-1826Network attack vector

Arbitrary cross-link creation via missing CSRF check

Published Jun 20, 2022 · Updated Aug 3, 2024

CSRF in Jan Hvizdak Cross-Linker 3.0.1.9 and earlier allows remote attackers to create arbitrary cross-links via an administrator's browser. The administrative cross-link creation action processes submitted link data without validating a CSRF nonce before saving it. Exploitation requires a logged-in administrator to submit an attacker-controlled request, enabling unauthorized changes to site link content.
