CVE-2024-29182Network attack vector

Browser script execution via unsanitized tooltip text

Published Apr 4, 2024 · Updated Aug 2, 2024

Stored XSS in Collabora Online 23 before 23.05.10.1 allows remote attackers to execute script via a crafted document tooltip. Document text referenced by a field is inserted into a tooltip without neutralizing script-related HTML, so hovering renders and executes the payload. A victim must open the malicious document and hover over the field; successful exploitation runs script in the browser context, enabling data reads or actions available to that session.
