Affected versions: *-1.7.7; *-10.42; *-3.5.0; *-1.3.0; *-1.0.7; *-1.5.0; *-3.3.5; *-1.2.9
Vulnerability type: CWE-862 Missing Authorization
Affected software, patched versions and attribution
The Appsero analytics tool used in several plugins is vulnerable to unauthorized modification of data due to a missing capability check on the handle_optin_optout function in versions up to, and including, 2.0.0. This makes it possible for unauthenticated attackers to opt-in or opt-out of tracking. This was patched in version 2.0.1 of Appsero with a nonce check.
