Short explanation
YesWiki prior to version 4.7.0 contains a stored cross-site scripting vulnerability via the ImageField SVG upload feature. Low-privilege authenticated users can upload unsanitized SVG files through the entries API [S0, S1].
Allowing authenticated users to submit malicious SVG files results in script execution within the browsers of anyone viewing the affected entry or file [S0, S1].
What should be done?
- Follow vendor advisories as patch status could not be reliably verified [S0]
- Review the published security advisories [S0, S1]
