CVE-2024-51508Public exploitNetwork attack vector

Stored script execution via External Wiki Index

Published Oct 28, 2024 · Updated Oct 29, 2024

Stored XSS in Tiki Wiki CMS Groupware through 27.0 allows remote authenticated users to execute script in an Index viewer's browser. The Create/Edit External Wiki workflow stores unsanitized payload content that the Index later renders as active page markup. The attacker needs specific content permissions, and exploitation requires another user to view the affected Index entry; the published impact is limited to browser-side confidentiality and integrity.
