AI-suggested

Users should update to version 3.2.5 where the issue was fixed. However, since the vulnerability was reintroduced in later versions, users must verify that they are running a version without this flaw or temporarily disable the extension until a new fix is released. Monitor official PIA communications for updated patches addressing the reintroduced vulnerability.

Description

The Private Internet Access (PIA) Extension for Firefox has an unguarded onAuthRequired authentication handler that can leak PIA proxy credentials when a user visits a malicious website issuing a Basic authentication challenge. This vulnerability was fixed in version 3.2.5 but was reintroduced in later versions.
