=== What is the potential impact?
|
|
|
|
An insecure Content Security Policy (CSP) can increase the potential severity of
|
|
other vulnerabilities in the system. For instance, if an attacker manages to
|
|
exploit a Cross-Site Scripting (XSS) vulnerability, an insecure CSP might not
|
|
provide the intended additional protection.
|
|
|
|
The impact of a successful XSS attack can be severe. XSS allows an attacker to
|
|
inject malicious scripts into web pages viewed by other users. These scripts can
|
|
then be used to steal sensitive information like session cookies, personal data,
|
|
or credit card details, leading to identity theft or financial fraud.
|
|
|
|
Moreover, XSS can be used to perform actions on behalf of the user without their
|
|
consent, such as changing their email address or password, or making
|
|
transactions. This can lead to unauthorized access and potential loss of control
|
|
over user accounts.
|
|
|
|
In addition, an insecure CSP that allows loading resources from arbitrary
|
|
domains could potentially expose sensitive user data to untrusted sources. This
|
|
could lead to data breaches, which can have serious legal and reputational
|
|
consequences.
