Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Grav CMS (getgrav/grav) versions from 2.0.10 before 2.0.11 contain a path traversal flaw in the watermark image action. A user with page-editing rights can use a crafted Markdown image reference to expose image files from outside the media folder through a publicly cached URL. Upgrade to 2.0.11.
