Vulnerabilities Splunk, Zoom Patch Critical Vulnerabilities The flaws could allow attackers to access credentials and data, take over accounts, and escalate their privileges. By Ionut Arghire | July 16, 2026 (6:54 AM ET) Flipboard Reddit Whatsapp Whatsapp Email Splunk and Zoom this week announced patches for multiple vulnerabilities across their products, including several critical and high-severity security defects. Only three of the five advisories that Splunk published address flaws that are specific to its products, while the other two resolve dozens of bugs in third-party components. The Splunk-specific issues include CVE-2026-20296 (a high-severity command safeguards bypass), CVE-2026-20297 (a high-severity path traversal), and CVE-2026-20298 (a medium-severity information disclosure). Successful exploitation of these weaknesses could allow attackers to access credentials and data, write files outside the intended application directory, and view stored credential hashes. Patches for all three were included in Splunk Enterprise versions 10.4.1, 10.2.5, 10.0.8, and 9.4.13, which also address critical- and high-severity vulnerabilities in Golang, Go compiler, OpenSSL, and other third-party libraries. Zoom published four advisories that resolve as many vulnerabilities across its clients and tools for Windows. Advertisement. Scroll to continue reading. The most severe is CVE-2026-53412 (CVSS score of 9.8), a critical bug in Zoom’s Workplace and Workplace VDI Client for Windows that could allow remote, unauthenticated attackers to mount account takeover attacks. The company’s updates also resolve three high-severity flaws: a time-of-check-to-time-of-use (TOCTOU) race condition and two privilege elevation issues. Neither Splunk nor Zoom makes any mention of these vulnerabilities being exploited in the wild.
