CVE-2026-62324: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in xdan jodit
Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. Prior to 4.12.31, Jodit's sanitizeHTMLElement method fails to use isDangerousUrl to normalize javascript: href values before checking the scheme, allowing case variants, control-byte prefixes, and embedded tabs or newlines to bypass filtering and execute attacker-controlled script when a victim clicks a stored link rendered by an application. This issue is fixed in version 4.12.31.
AI Analysis
Technical Summary
The vulnerability in Jodit Editor arises from the sanitizeHTMLElement method not properly using the isDangerousUrl function to normalize javascript: href values before scheme checking. This allows bypasses using case variants, control-byte prefixes, and embedded tabs or newlines, enabling stored XSS attacks when a victim interacts with a malicious link rendered by an application using the affected versions. The issue is resolved in version 4.12.31.
Potential Impact
Successful exploitation can lead to limited confidentiality and integrity impacts via stored cross-site scripting, where attacker-controlled scripts execute in the context of the victim's browser upon clicking a malicious link. There is no impact on availability. The CVSS score is 5.4 (medium severity).
Mitigation Recommendations
Upgrade to Jodit Editor version 4.12.31 or later, where the vulnerability is fixed. No other mitigation guidance is provided or required.
