SQL injection vulnerability in the photo-edit subsystem in Piwigo 2.6.x and 2.7.x before 2.7.0beta2 allows remote authenticated administrators to execute arbitrary SQL commands via the associate[] field.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
