Description
The vulnerability allows a remote attacker to bypass the CORS protection mechanism.
The vulnerability exists due to incorrect processing of the "Origin" HTTP header that is supplied within HTTP request in Sentry API. A remote attacker can supply arbitrary value via the "Origin" HTTP header, bypass implemented CORS protection mechanism and perform cross-site scripting attacks against the vulnerable application.
Note, the vulnerability affects installations only that have `system.base-hostname` option explicitly set, as it is empty by default.
Remediation
