CVE-2021-32723 (GCVE-0-2021-32723)

Vulnerability from cvelistv5 – Published: 2021-06-28 19:15 – Updated: 2024-08-03 23:33

Title

Regular Expression Denial of Service (ReDoS) in Prism

Summary

Prism is a syntax highlighting library. Some languages before 1.24.0 are vulnerable to Regular Expression Denial of Service (ReDoS). When Prism is used to highlight untrusted (user-given) text, an attacker can craft a string that will take a very very long time to highlight. This problem has been fixed in Prism v1.24. As a workaround, do not use ASCIIDoc or ERB to highlight untrusted text. Other languages are not affected and can be used to highlight untrusted text.

Severity

7.4 (High)
