Hi,
The following vulnerability was published for pygments.
CVE-2021-27291[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
