netresearch/rte-ckeditor-image is vulnerable to Cross-site Scripting (XSS)
56
Medium Risk
This Affects:
netresearch/rte-ckeditor-imageTL;DR
Affected versions of this package are vulnerable to cross-site scripting (XSS) via unsanitized SVG data URIs, because data:image/svg+xml sources could contain embedded JavaScript (such as <script> tags, event handlers, or javascript: hrefs) that bypass normal upload validation. The patched version adds runtime sanitization of SVG data URIs using the TYPO3 core SvgSanitizer, ensuring that malicious content is removed before rendering. This mitigation prevents XSS attacks via inline SVG payloads in image sources.
