Name of the Vulnerable Software and Affected Versions ReportLab versions prior to 3.5.31

Description The issue is related to the start unichar function in paraparser.py, which incorrectly processes XML documents. This allows a remote attacker to execute arbitrary code by crafting a malicious XML document with a <unichar code> element containing Python code.

Recommendations For versions prior to 3.5.31, update to version 3.5.31 or later to resolve the issue. As a temporary workaround, consider restricting the use of the start unichar function in paraparser.py to minimize the risk of exploitation. Avoid evaluating untrusted user input in the unichar element of XML documents until the issue is resolved.
