+description=Ensure that the MAP parameter is restricted to safe values.
+about=This QGIS server plugin ensures that the MAP=... parameter always matches `[-_a-z0-9]+`, suffixes it with `.qgs` and prefixes it with PROJECT_PREFIX and the value itself as a directory name. Invalid values are removed to mitigate malicious requests.
