DescriptionCVE.org

An issue in ClipBucket v5 v.5.5.2 allows an attacker to execute arbitrary code via the Authentication interface, login page endpoint and HTTP response security headers components

AnalysisAI

Clickjacking in ClipBucket v5 5.5.2 lets an attacker embed the application's login page in a hidden iframe due to missing HTTP response security headers, enabling UI-redressing attacks that can capture credentials or trick authenticated users into unintended actions. The flaw is classified CWE-1021 (Improper Restriction of Rendered UI Layers), not the 'arbitrary code execution' the raw description claims — the referenced technical writeup and the CVSS profile (UI:R) both point to a framing/credential-theft issue. EPSS is very low (0.05%, 14th percentile) and CISA SSVC scores exploitation as 'none', indicating no observed active exploitation.
