CVE-2022-25979Public exploitNetwork attack vector

Script execution via skipped single-attribute sanitization

Published Jan 31, 2023 · Updated Mar 27, 2025

Cross-site scripting in the jSuites Editor before 5.0.1 allows remote attackers to execute script in a user's browser through pasted HTML. The Editor() sanitizer skips attribute filtering when a pasted element has only one attribute, allowing crafted markup and an event handler to survive. Exploitation requires a user to paste attacker-supplied HTML into an application embedding the affected editor, enabling script execution in that application's origin.
