topydo fixed: Latest secure release 
pip install topydo>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show topydo

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2018-1000523, inspect your installed packages using pip:

pip show topydo

Analyze the terminal output to locate any version of Topydo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show topydo command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Topydo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

topydo contains a CWE-20: Improper Input Validation vulnerability in `ListFormatParser::parse`, file `topydo/lib/ListFormat.py` line 292 as of d4f843dac71308b2f29a7c2cdc76f055c3841523 that can result in Injection of arbitrary bytes to the terminal, including terminal escape code sequences. This attack appear to be exploitable via The victim must open a todo.txt with at least one specially crafted line.
