Reflected script execution via unsanitized invitation code
Published Apr 22, 2021 · Updated Aug 3, 2024
Pie Register before 3.7.0.1 allows remote attackers to execute script in a victim browser via a crafted invitaion_code parameter. The Activation Code page outputs that GET parameter without sanitization, so attacker-controlled markup is reflected into the response. Exploitation requires a victim to request the crafted URL; the documented impact is script execution in the victim’s browser with confidentiality and integrity effects, not service interruption.
