Advisory Published
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 (CVE-2021-27291).
