SHIRASAGI prior to v1.19.1 processes URLs in HTTP requests improperly, resulting in a path traversal vulnerability. If this vulnerability is exploited, arbitrary files on the server may be retrieved when processing crafted HTTP requests.

SHIRASAGI is a Content Management System. Prior to version 1.18.0, SHIRASAGI is vulnerable to a Post-Unicode normalization issue. This happens when a logical validation or a security check is performed before a Unicode normalization. The Unicode character equivalent of a character would resurface after the normalization. The fix is initially performing the Unicode normalization and then strip for all whitespaces and then checking for a blank string. This issue has been fixed in version 1.18.0.

Stored cross-site scripting vulnerability in SHIRASAGI prior to v1.18.0 allows a remote authenticated attacker to execute an arbitrary script on the web browser of the user who is logging in to the product.
