CVE-2020-9426Public exploitNetwork attack vector

Cross-site scripting via crafted guard input

Published Jun 15, 2020 · Updated Aug 4, 2024

Cross-site scripting in OX Guard 2.10.3 and earlier allows remote attackers to execute script in a victim's browser via crafted input. The guard component renders attacker-controlled content without sufficient output encoding, allowing script execution in the browser context. Exploitation requires a victim to open the affected content; reported impact is client-side confidentiality and integrity exposure without service interruption.
