Unauthorized order cancellation via state-changing GET handlers
Published Jul 21, 2026 · Updated Jul 21, 2026
Cross-site request forgery in DjangoSIGE through 1.10 allows remote attackers to cancel sales or purchase orders through a victim's session. Four Cancelar order views perform cancellation in get() handlers, so Django's CSRF middleware never validates a token. Exploitation requires an authenticated victim with the relevant change permission to load an attacker-controlled page, and the bounded impact is unauthorized order cancellation.
