Answer in brief
CVE-2026-13513 records a Medium severity (CVSS 5.0) vulnerability in MyScale MyScaleDB SegmentId.h getCacheKey data authenticity. The current sources do not mark it as known exploited. The current feed maps MyScale/MyScaleDB (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.0. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
