CVE-2024-38517: Tencent Rapidjson

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

Tencent RapidJSON is vulnerable to privilege escalation due to an integer underflow in the `GenericReader::ParseNumber()` function of `include/rapidjson/reader.h` when parsing JSON text from a stream. An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer underflow vulnerability (when the file is parsed), leading to elevation of privilege.

Affected products

• Tencent Rapidjson: up to and including 1.1.0
