What is CVE-2018-13863?

The MongoDB bson JavaScript module, specifically within versions 0.5.0 to 1.0.x before 1.0.5, is susceptible to a Regular Expression Denial of Service (ReDoS) attack. This vulnerability is triggered when the Decimal128.fromString() function processes long untrusted strings, leading to potential denial of service conditions. The flaw stems from insufficient validation of the input, allowing attackers to craft specific input strings that can significantly degrade system performance and availability.
