Detailed vulnerability description
The vulnerability allows a remote attacker to bypass filtration.
The vulnerability exists due to insufficient validation of user-supplied input when parsing email address with a special character. A remote attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain.
How to mitigate CVE-2023-27043
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
