Detection is best done via a command line of grep -rE \"cpanel_jsonapi_func=redisAble\" /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null in Bash. If you get no output, you have not been hit with exploitation of the vulnerability. If there is output, we recommend you examine the IP addresses in the list, determine if they are valid IP addresses, and if not, block them. To determine damage done, examine the system logs for use by the detected IP addresses. The issue is related to mishandling of Redis enable/disable features. The recommended minimum version is 2.4.7."}],"metrics":[{"cvssV4_0":{"Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","Safety":"NOT_DEFINED","attackComplexity":"LOW","attackRequirements":"NONE","attackVector":"NETWORK","baseScore":10,"baseSeverity":"CRITICAL","privilegesRequired":"NONE","providerUrgency":"NOT_DEFINED","subAvailabilityImpact":"HIGH","subConfidentialityImpact":"HIGH","subIntegrityImpact":"HIGH","userInteraction":"NONE","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0","vulnAvailabilityImpact":"HIGH","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnerabilityResponseEffort":"NOT_DEFINED"},"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}]}],"problemTypes":[{"descriptions":[{"cweId":"CWE-266","description":"CWE-266 Incorrect Privilege Assignment","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","shortName":"mitre","dateUpdated":"2026-05-24T23:05:58.862Z"},"references":[{"url":"https://www.litespeedtech.com/products/litespeed-web-server/control-panel-support/cpanel"},{"url":"https://www.litespeedtech.com/products/litespeed-web-server/control-panel-support/release-log"},{"url":"https://blog.litespeedtech.com/2026/05/21/security-update-for-litespeed-cpanel-plugin/"}],"solutions":[{"lang":"en","supportingMedia":[{"base64":false,"type":"text/html","value":"Installation of LiteSpeed WHM PlugIn 5.3.1.0 and cPanel 2.4.7.  Though installation of WHM 5.2.10 and cPanel 2.4.5 and above mitigate most of the issues."}],"value":"Installation of LiteSpeed WHM PlugIn 5.3.1.0 and cPanel 2.4.7.  Though installation of WHM 5.2.10 and cPanel 2.4.5 and above mitigate most of the issues."}],"tags":["x_known-exploited-vulnerability"],"x_generator":{"engine":"CVE-Request-form 0.0.1"}},"adp":[{"references":[{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-48172","tags":["government-resource"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-21T00:00:00+00:00","options":[{"Exploitation":"active"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-48172"}}},{"other":{"type":"kev","content":{"dateAdded":"2026-05-26","reference":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-48172"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-27T03:55:24.811Z"},"timeline":[{"time":"2026-05-26T00:00:00.000Z","lang":"en","value":"CVE-2026-48172 added to CISA KEV"}]}]},"dataVersion":"5.2"}
