This omission allows an attacker to embed crafted relative links inside a collaborative document.

The resulting behaviour can trigger forced actions, create misleading or spoofed content, and lead to a persistent denial\u2011of\u2011service condition.\n\nThe weakness is a classic example of insecure input validation (CWE\u2011345).
