Apache has released DataSketches C++ 5.3.0, fixing three deserialization vulnerabilities in the datasketches-cpp library that affect all versions up to 5.2.0. Two flaws, tracked as CVE-2026-103501 and CVE-2026-103513, can cause heap corruption, while CVE-2026-103635 allows an out-of-bounds read. All three can be triggered by crafted sketch data, so users are urged to upgrade.
