Vulnerability from github – Published: 2026-09-25 15:00 – Updated: 2026-09-25 15:00

Summary

code16/sharp has a stored XSS via data-html-content Sanitizer Bypass

Details

Impact

The vulnerability allows an attacker to bypass the HTML sanitizer by using the data-html-content attribute in the content of a SharpEditorFormField.

Patches

The field must now explicitly configure SharpFormEditorField::RAW_HTML in the toolbar to keep this behavior. When using the RAW_HTML button, the application using code16/sharp must sanitize manually the content coming from the field. Vulnerability has been patched in version 9.22.5.

Workarounds

Sanitize every contents of editors manually (e.g. using Symfony/HtmlSanitizer)

Severity

8.7 (High)

CVE-2026-61825 (GCVE-0-2026-61825)

Vulnerability from cvelistv5 – Published: 2026-09-24 18:27 – Updated: 2026-09-24 18:53

Title

code16/sharp has a stored XSS via data-html-content Sanitizer Bypass

Summary

code16 Sharp is a Laravel-based framework for building content-management and administrative interfaces. Versions before 9.22.5 contain a stored cross-site scripting vulnerability in `SharpEditorFormField`: attacker-controlled content bearing the `data-html-content` attribute can bypass HTML sanitization and preserve executable markup, which may execute when another user views the stored content. The vendor identifies version 9.22.5 as patched; applications that intentionally enable `SharpFormEditorField::RAW_HTML` must continue to sanitize editor content themselves. As a workaround, applications should sanitize all editor content before storing or rendering it, for example with Symfony HtmlSanitizer, and disable RAW_HTML functionality where it is not required.

Severity

8.7 (High)
