GMS-2019-117: Regular Expression Denial of Service in braces

June 6, 2019 (updated August 4, 2021)

Versions of braces prior to 2.3.1 are vulnerable to Regular Expression Denial of Service (ReDoS). Untrusted input may cause catastrophic backtracking while matching regular expressions. This can cause the application to be unresponsive leading to Denial of Service.

Recommendation

Upgrade to version 2.3.1 or higher.
