Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
grafana12.4:
* grafana12.4-12.4.10-0.1.hum1 (aarch64, x86_64)
* grafana12.4-12.4.10-0.1.hum1.src (src)

A flaw in Grafana allows authenticated 'Editor' users to inject malicious scripts into a table panel's field names. Viewing the compromised dashboard executes the script in the victim's browser, risking data theft or client-side attacks.

Threats
Impact
Moderate
A flaw was found in Grafana. An unauthenticated attacker can repeatedly access the OAuth login route with unique values. This can lead to unbounded memory growth, eventually exhausting system memory and causing the Grafana instance to crash. This results in a denial of service for legitimate users.
5.3 (Medium)
Affected products
Fixed
3 products, the same list as for
CVE-2026-8595
Threats
Impact
Moderate
A flaw was found in Grafana. This vulnerability, categorized as broken access control, allows an attacker to bypass security mechanisms in a web application. This can lead to unauthorized access to sensitive data, enable operations on behalf of other users, and potentially result in privilege escalation or account takeovers.
8.3 (High)
Affected products
Fixed
3 products, the same list as for
CVE-2026-8595
Threats
Impact
Important
A flaw was found in Grafana. An authenticated attacker with Editor access or `alert.instances.external:write` permissions can submit an external Alertmanager alert containing a controlled `generatorURL`. Grafana improperly renders this URL without proper sanitization, allowing for a bypass of the click interceptor's security heuristic. This can lead to a Cross-Site Scripting (XSS) vulnerability, where a user with read access who clicks the 'See source' link will execute attacker-controlled JavaScript in their browser with the permissions of the clicking user, potentially leading to information disclosure or unauthorized actions.
6.8 (Medium)
Affected products
Fixed
3 products, the same list as for
CVE-2026-8595
Threats
Impact
Moderate
A flaw was found in Grafana's Unified Alerting component. An authenticated user with permissions to create or edit alert rules in a folder can bypass datasource query permissions. By manipulating the `queryType` field, an attacker can execute queries against datasources they are not authorized to access, leading to the disclosure of sensitive data. This vulnerability arises from inconsistent query classification between authorization and execution paths.
7.1 (High)
Affected products
Fixed
3 products, the same list as for
CVE-2026-8595
Threats
Impact
Important
A flaw was found in Grafana. A remote attacker with very low privileges, or even anonymous access if enabled, can exploit the alertmanager templates test endpoint by mass-executing templates. This can lead to an Out-Of-Memory (OOM) error, causing the Grafana service to crash and resulting in a Denial of Service (DoS).
5.3 (Medium)
Affected products
Fixed
3 products, the same list as for
CVE-2026-8595
Threats
Impact
Moderate
A flaw in Grafana's API endpoints allows remote attackers to send excessively large request bodies without authentication. This exhausts server memory, resulting in a complete denial of service (DoS).

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
