|---|---|---|---|---|---|---|---|
| CVE-2026-4539 | Low | 3.3 | < 2.20.0 | 2.20.0 | Mar 22, 2026 | A security flaw has been discovered in pygments up to 2.19.2. The impacted element is the function AdlLexer of the file pygments/lexers/archetype.py. The manipulation results in inefficient regular expression complexity. The attack is only possible with local access. The exploit | |

| CVE-2021-20270 | — | >= 1.5, < 2.7.4 | 2.7.4 | Mar 23, 2021 | An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword. | ||
| CVE-2021-27291 | — | >= 1.1, < 2.7.4 | 2.7.4 | Mar 17, 2021 | 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 | ||
