Deeper analysis
CVE-2022-43568 is a reflected cross-site scripting vulnerability (CWE-79) present in Splunk Enterprise versions below 8.1.12, 8.2.9, and 9.0.2. The flaw resides in a View component that processes a JSON-formatted query parameter when the output_mode is set to radio, allowing attacker-controlled script to be reflected back to the user without adequate sanitization.
An unauthenticated remote attacker can exploit the issue by crafting a malicious URL containing the JSON payload and luring a victim into clicking it. Successful exploitation grants the attacker the ability to execute arbitrary JavaScript in the victim's browser session, potentially leading to theft of session tokens, account takeover, or other actions within the Splunk interface with a CVSS score of 8.8.
Splunk's security advisory SVD-2022-1108 and accompanying research note direct customers to upgrade to the fixed releases 8.1.12, 8.2.9, or 9.0.2; no workarounds are specified in the published references.
The EPSS score for this CVE rose from a low baseline to a peak of 0.3844 on 2025-12-11 before receding to the current value of 0.1211, indicating a period of increased exploitation interest after disclosure.
