Machine-written summary

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

CodeIgniter Rest Server (chriskacerguis/codeigniter-restserver) versions before 2.7.2 are vulnerable to XML external entity (XXE) attacks. The source gives few details about the attack conditions, but an XXE flaw can let an attacker read files or make server-side requests. Upgrade to version 2.7.2, which is the listed fix.
