An improper neutralization of special elements used in an SQL command in the papertrail/version- model of the decidim_awesome-module <= v0.11.1 (> 0.9.0) allows an authenticated admin user to manipulate sql queries to disclose information, read and write files or execute commands.
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.
