CVE-2024-56359Network attack vector

Account compromise via unsanitized HyperLink URL

Published Dec 20, 2024 · Updated Dec 24, 2024

Cross-site scripting in Grist Labs grist-core before 1.3.2 allows remote attackers to compromise accounts through crafted HyperLink cells. The HyperLinkTextBox renderer passed a constructed cell URL directly to an anchor without validating its scheme, allowing javascript: code to run in the Grist page origin. Exploitation requires a user to open an untrusted document and control-click its crafted link; merely viewing the document does not trigger the code.
