CVE-2026-9029

A flaw was found in the Grafana geomap panel's XYZ tile layer. An attacker with editor privileges can exploit a sanitize-then-interpolate ordering bug by setting a textbox variable's default value to a Cross-Site Scripting (XSS) payload. This payload executes for every user who opens the dashboard, potentially leading to arbitrary code execution and information disclosure.

Threats
Impact Important
CVE-2026-10601

A flaw was found in the Tempo and Loki datasource plugins. A remote attacker with a Viewer role could exploit a path traversal vulnerability by manipulating user-supplied input in URL paths. This could allow the attacker to capture sensitive administrator-configured datasource credentials, invoke state-changing administrative functions on Tempo, or exfiltrate internal service data from Loki.

5.4 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Affected products
Fixed 3 products, the same list as for CVE-2026-9029
Threats
Impact Moderate
CVE-2026-75838

A flaw was found in DOMPurify. This cross-site scripting vulnerability occurs during IN_PLACE sanitization, where element-removal hooks fail to neutralize detached subtrees. A remote attacker can exploit this by supplying specially crafted HTML with event handlers. This allows the execution of malicious scripts even after the HTML appears to be sanitized, leading to potential information disclosure or unauthorized actions.

6.1 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Affected products
Fixed 3 products, the same list as for CVE-2026-9029
Threats
Impact Moderate
CVE-2026-90771

A flaw was found in joi. This vulnerability, known as prototype pollution, exists in the messages compilation function. A remote attacker can exploit this by supplying specially crafted `__proto__` keys in custom messages. This allows the attacker to manipulate object properties, which could lead to unexpected application behavior or crashes.

5.9 (Medium)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes
Affected products
Fixed 3 products, the same list as for CVE-2026-9029
Threats
Impact Moderate
