In haml versions prior to version 5.0.0.beta.2, when using user input to perform tasks on the server, characters like < > " ' must be escaped properly. In this case, the ' character was missed. An attacker can manipulate the input to introduce additional attributes, potentially executing code.

From the Ubuntu Security Team

It was discovered that Haml did not properly escape the ' character. If Haml were made to process crafted data, an attacker could execute arbitrary code.
