Note deletion via unprotected GET request

Published Sep 9, 2023 · Updated Aug 2, 2024

Cross-site request forgery in SourceCodester Take-Note App 1.0 allows remote attackers to delete notes through a crafted link. The endpoint/delete_note.php handler accepts a note identifier in the delete query parameter and performs deletion through a GET request without validating request provenance. A victim with an active application session must follow the attacker-supplied link, after which the targeted note is deleted.
