Block Wiki resource: Wiki configuration: Disable the option "Enable Wiki resource" to block the Wiki system-wide. The Wiki component is currently still vulnerable to cross-site scripting attacks (XSS). Therefore the XSS scanner can be activated additionally. This can lead to impairments in the Wiki functionality in OpenOLAT. If the XSS scanner is switched off, the Wiki can be used with the risk of an XSS attack. However, the Wiki component has automatic versioning, which makes it difficult for attackers to remain undetected.
