CVE-2021-36785Network attack vector

Browser script execution via unsanitized SAML attributes

Published Aug 13, 2021 · Updated Aug 4, 2024

Cross-site scripting in miniOrange SAML before 1.4.3 for TYPO3 allows remote authenticated users to execute script via SAML attributes. The TestResultActions template inserts SAML NameID and attribute values into generated HTML without removing markup. Exploitation requires low-privileged access and a victim to view the test-result page, allowing script execution in that viewer's browser context.
