OpenSea fixes a major vulnerability that could have leaked your identity

• The loophole at OpenSea, when exploited, could have enabled the attacker to obtain users’ identities.
• OpenSea quickly fixed the problem after the vulnerability came to light.

Cyber ​​security company Imperva discovered a major vulnerability in the popular NFT marketplace OpenSea, which, if successfully exploited, could allow an attacker to obtain the identity of users on the platform.

According to Imperva, the misconfiguration of the iFrame-resizer library used by OpenSea was the main reason behind the vulnerability.

Providing more details on the exploit mechanism for the issue, Imperva stated that the attacker would send a link via email or SMS.

If the victim clicks on the link, important information such as the target’s IP address, user agent, device details and software versions will be retrieved.

Cross-site search vulnerability would then be exploited to obtain the target’s NFT name, and the attacker would then link the leaked NFT/public wallet address to the email or phone number to which the link was originally sent.

However, Imperva’s report mentioned that OpenSea had fixed the problem after it was reported and that the marketplace was no longer vulnerable to such attacks
