Multiple vulnerabilities have been identified in Photo Album (plugin for WordPress), which could be exploited by remote attackers to execute arbitrary SQL queries. These issues are caused by input validation errors in the “wppa.php” script when passing user-supplied parameters (e.g. “photo” or “album”) to certain functions (e.g. “wppa_album_name()” or “wppa_photo_name()”), which could be exploited by malicious people to conduct SQL injection attacks.

Multiple security advisory services places this round of vulnerabilities as a Moderate Risk. For example, FrSIRT describes the Moderate risk as being:

Remotely and locally exploitable flaws, which could lead to denial of Service or privilege escalation.

Versions 1.1 and prior of this plugin are vulnerable. As always, it is recommended that you disable this plugin until a patch for it is released.

[EDIT] Version 1.1 is a fix for this vulnerability. Versions 1.0 and prior might be vulnerable.
