phpBB 3.0.13 Release - Please Update

Post by naderman »

Greetings all,

We are pleased to announce the "Return of the Bertie" release of phpBB 3.0.13. This version is a security and maintenance release of the 3.0.x branch which hardens phpBB against potential attacks and fixes a number of bugs. You do not need to install this update if you are running phpBB 3.1.x.

The first vulnerability is a CSRF potentially allowing an attacker to modify the private message setting that determines how full folders are handled (i.e. whether to delete the oldest message or hold the new message until further space is available). Users FBNeal and lampsys independently reported the issue to us.

The second issue, reported to us by James Kettle, allows an attacker to load arbitrary CSS in Internet Explorer by crafting a URL with trailing paths after a PHP file (for example /path/index.php/more/path). This is only possible if the webserver configuration allows accessing PHP files in this manner. This can be exploited directly on Internet Explorer 7 or below, and on newer versions of Internet Explorer by using a frame that forces outdated rendering behavior.

Neither of these issues affects phpBB 3.1.x.

Thank you to James Kettle, FBNeal, and lampsys for responsibly reporting these issues to us.

This release further improves compatbility with PHP 5.6, Apache 2.4, Internet Explorer 11, and Microsoft Azure.

The full changelog is available in the changelog file within the docs folder contained in the release package. You can find the key highlights of this release on the wiki at and a list of all issues fixed on our tracker at

The packages can be downloaded from our downloads page.

The development team thanks everyone who contributed code to this release: Oliver Schramm, erangamapa, Crizzo, s9e, Vjacheslav Trushkin, Jakub Senko, geetakshi, Marcos Bjorkelund, Marcus Vinicius, Matt Friedman, n-aleha, rechosen, Daniel Schosser, David Prévot, Falk Seidel, Igor Wiedler, Mario Skouat, Prosk8er

If you have any questions or comments, we'll be happy to address them in the discussion topic.
