Description Ronit Dey 2026-10-28 13:44:14 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A security vulnerability has been detected in Tencent RapidJSON up to 1.1.0. This issue affects the function GenericStringStream<UTF8<char>>::Take in the library include/rapidjson/stream.h of the component Regex Parser. The manipulation leads to out-of-bounds read. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.

Comment 1 Michal Schorm 2026-10-28 15:13:16 UTC
MySQL bundles a specific rapidjson version (commit `06d58b9e848c650114556a23294d0b6440078c61`) with custom patches
MySQL 9.7.4 (released 2026-10-20) still bundles the vulnerable commit.

The CVE is in the upstream rapidjson library, but it is not yet fixed:
