Analyst Note

CVE-2021-22175 was added to CISA's Known Exploited Vulnerabilities Catalog, indicating active exploitation in the wild. Published June 2021 with evidence of real-world attacks, this meets the zero-day criteria of in-the-wild exploitation. However, the lack of explicit timing confirmation that exploitation preceded patch availability and absence from Project Zero slightly tempers confidence.
