Announcements

This release fixes CVE-2024-2410 (note: there may be a delay in the publication of this CVE number), a minor vulnerability in the C++ JSON parser. In certain situations, a malicious JSON input could cause the parser to copy data that has already been freed into an error message. This can only happen if the code is parsing from a stream with separate chunks rather than a contiguous array. The bug was introduced in 4.22.0 and was fixed with b955165 in 4.25.0 and up.
