phpBB forum fixes auth bypass bug lurking for a decade

By Bill Toulas

AI Summary

A 10-year-old authentication bypass vulnerability in phpBB forum software has been patched, allowing an unauthenticated attacker to log in as any account including site administrators. The flaw had been present and undetected in the widely deployed open-source forum platform for a decade, posing a significant risk to any phpBB instance that had not applied the fix. Forum operators should update immediately, as the bug's severity and long exposure window make it likely to be actively targeted following public disclosure.
