CVE-2026-20257 MEDIUM PATCH This Month

Classic dashboard style attribute injection in Splunk Enterprise and Splunk Cloud Platform enables a low-privileged authenticated user to craft panels that bypass the Trusted Domains List and exfiltrate sensitive data from a higher-privileged user's browser session. Affected branches span Splunk Enterprise below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and multiple Splunk Cloud Platform release trains. No public exploit has been identified at time of analysis, and SSVC rates current exploitation as none with partial technical impact, though the high confidentiality impact potential warrants prompt patching in environments where low-privileged users can share dashboards with administrators.

CVE-2026-20259 MEDIUM PATCH This Month

Improper access control on the saved search ownership reassignment endpoint in Splunk Enterprise and Splunk Cloud Platform allows a highly privileged authenticated user - one whose role contains the `edit_saved_search_owner` capability - to reassign saved search ownership to users outside their authorized scope. Affected versions span Splunk Enterprise below 10.2.4 and 10.0.7, and multiple Splunk Cloud Platform branches below their respective fixed builds. No public exploit has been identified at time of analysis, and the PR:H CVSS requirement confines risk primarily to insider threats or scenarios involving compromised privileged Splunk accounts.

CVE-2026-20255 MEDIUM PATCH This Month

Classic dashboard URL validation bypass in Splunk Enterprise and Splunk Cloud Platform enables low-privileged authenticated users to craft dashboards that silently exfiltrate sensitive data to attacker-controlled external servers. The flaw (CWE-20) resides in the external content dialog, which fails to enforce complete domain restrictions, allowing outbound requests to untrusted hosts when a victim interacts with the malicious dashboard. No public exploit exists and this vulnerability is not listed in CISA KEV, but the High confidentiality impact (C:H) in the CVSS vector reflects meaningful data exposure risk in environments where Splunk indexes security events, credentials, or sensitive operational logs.

CVE-2026-20254 MEDIUM PATCH This Month

CSS injection in Splunk Enterprise and Splunk Cloud Platform classic dashboards enables credential and sensitive data exfiltration by low-privileged users targeting higher-privileged accounts. A low-privileged user (without 'admin' or 'power' roles) can craft a malicious classic dashboard containing injected CSS via inline style attributes; when a higher-privileged user views the dashboard, outbound HTTP requests are triggered to attacker-controlled external servers, bypassing the Trusted Domains restriction. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog, but the C:H confidentiality impact and cross-privilege exploitation path make this a meaningful insider or compromised-account threat in environments with mixed privilege levels.

CVE-2026-20256 MEDIUM PATCH This Month

Classic dashboard drill-down links in Splunk Enterprise and Splunk Cloud Platform can be weaponized by low-privileged authenticated users to silently redirect victims to attacker-controlled external sites, enabling data exfiltration. The flaw stems from an incomplete URL scheme validator that recognizes only 'http://' and 'https://' prefixes, allowing protocol-relative URLs like '//attacker.com' to bypass the external-navigation warning dialog entirely. No public exploit code exists and no active exploitation is confirmed (not in CISA KEV), but the attack requires only a low-privileged account and a single victim click, making it a realistic phishing vector in multi-tenant or large enterprise Splunk deployments.
