CVE-2021-27291

A denial of service attack was discovered against pygments. Some of the regular expressions used to tokenise source code for highlighting have exponential complexity. A specially crafted input file could cause pygments to take effectively infinite time to parse, consuming CPU resources and denyin...

Regular Expression Denial Of Service (ReDoS)

pygments is vulnerable to regular expression denial of service. An attacker is able to crash the application by submitting a malicious string via Lexer for Values used in ADL and ODIN...

CVE-2021-27291

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...
