What is CVE-2026-95812?

ClipBucket versions prior to 5.5.3-#182 contain a reflected cross-site scripting vulnerability within the sort_link() helper function. This flaw arises because the application does not adequately sanitize user-supplied input from the 'cat', 'sort', and 'time' query parameters. As a result, attackers can create specially crafted requests that include malicious script payloads. If these requests are executed, they enable the execution of arbitrary JavaScript code in the browsers of unsuspecting users, potentially leading to unauthorized actions or data leakage.

Exploit Proof of Concept (PoC)
