Brave Discovers Vulnerability in Comet Browser or User Data Leak

According to reports from HashChain, Brave's research team has found a vulnerability in Perplexity AI's Comet browser that allows for prompt injection attacks, potentially leading to the leakage of users' personal data. Although Perplexity claims to have fixed the issue and denies any data leak, Brave indicates that the vulnerability could still be exploited, warning that such attacks pose a serious security threat to AI systems. To mitigate such risks, Brave plans to implement measures like isolated storage in its new browser.
