CriticalPHP2Shell is fixed, but a researcher now claims six more unpatched PHP flaws. Nothing to do today, but PHP is not out of the woodsWhat to prepare
CVE-2017-20279HighCVSS 8.8CVE published 19 June 2026

Payage (com_payage) <= 2.05 - Unauthenticated SQL Injection

Payage 2.05 and earlier concatenate the aid request parameter straight into a SQL query with no escaping. An unauthenticated attacker can read arbitrary data from the Joomla database, including the user table and its password hashes, with a single crafted GET request. No fix was published for the 2.0.x line. Update to a current Payage release, or uninstall the component if it is no longer used.

Is my site affected?

Affected
Payage up to and including 2.05
Fixed in
A release after 2.05
What to do
Update Payage to the newest release from the vendor. This flaw covers versions up to 2.05, so any later release is outside it.
