Quick fix
PYSEC-2021-141 — pygments: upgrade to the fixed version with the command below.
pip install --upgrade 'pygments>=2e7e8c4a7b318f4032493773732754e418279a14'Details
In pygments 1.1+, fixed in 2.7.4, the lexers used to parse programming languages rely heavily on regular expressions. Some of the regular expressions have exponential or cubic worst-case complexity and are vulnerable to ReDoS. By crafting malicious input, an attacker can cause a denial of service.
