| CVE-2026-40179 | 1 Prometheus | 1 Prometheus | 2026-04-17 | N/A |
| Prometheus is an open-source monitoring system and time series database. Versions 3.0 through 3.5.1 and 3.6.0 through 3.11.1 have stored cross-site scripting vulnerabilities in multiple components of the Prometheus web UI where metric names and label values are injected into innerHTML without escaping. In both the Mantine UI and old React UI, chart tooltips on the Graph page render metric names containing HTML/JavaScript without sanitization. In the old React UI, the Metric Explorer fuzzy search results use dangerouslySetInnerHTML without escaping, and heatmap cell tooltips interpolate le label values without sanitization. With Prometheus v3.x defaulting to UTF-8 metric and label name validation, characters like <, >, and " are now valid in metric names and labels. An attacker who can inject metrics via a compromised scrape target, remote write, or OTLP receiver endpoint can execute arbitrary JavaScript in the browser of any Prometheus user who views the metric in the Graph UI, potentially enabling configuration exfiltration, data deletion, or Prometheus shutdown depending on enabled flags. This issue has been fixed in versions 3.5.2 and 3.11.2. If developers are unable to immediately update, the following workarounds are recommended: ensure that the remote write receiver (--web.enable-remote-write-receiver) and the OTLP receiver (--web.enable-otlp-receiver) are not exposed to untrusted sources; verify that all scrape targets are trusted and not under attacker control; avoid enabling admin or mutating API endpoints (e.g., --web.enable-admin-api or --web.enable-lifecycle) in environments where untrusted data may be ingested; and refrain from clicking untrusted links, particularly those containing functions such as label_replace, as they may generate poisoned label names and values. | ||||
| CVE-2022-21698 | 4 Fedoraproject, Prometheus, Rdo Project and 1 more | 17 Extra Packages For Enterprise Linux, Fedora, Client Golang and 14 more | 2025-04-23 | 7.5 High |
| client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods. | ||||
| CVE-2023-40577 | 3 Debian, Prometheus, Redhat | 3 Debian Linux, Alertmanager, Openshift | 2025-02-13 | 7.5 High |
| Alertmanager handles alerts sent by client applications such as the Prometheus server. An attacker with the permission to perform POST requests on the /api/v1/alerts endpoint could be able to execute arbitrary JavaScript code on the users of Prometheus Alertmanager. This issue has been fixed in Alertmanager version 0.2.51. | ||||
| CVE-2023-26735 | 1 Prometheus | 1 Blackbox Exporter | 2025-02-04 | 7.5 High |
| blackbox_exporter v0.23.0 was discovered to contain an access control issue in its probe interface. This vulnerability allows attackers to detect intranet ports and services, as well as download resources. NOTE: this is disputed by third parties because authentication can be configured. | ||||
| CVE-2022-46146 | 2 Prometheus, Redhat | 2 Exporter Toolkit, Openshift | 2024-11-21 | 6.2 Medium |
| Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There is no workaround, but attacker must have access to the hashed password to use this functionality. | ||||
| CVE-2021-29622 | 2 Prometheus, Redhat | 2 Prometheus, Openshift | 2024-11-21 | 6.5 Medium |
| Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint. If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus. | ||||
| CVE-2020-16248 | 1 Prometheus | 1 Blackbox Exporter | 2024-11-21 | 5.8 Medium |
| Prometheus Blackbox Exporter through 0.17.0 allows /probe?target= SSRF. NOTE: follow-on discussion suggests that this might plausibly be interpreted as both intended functionality and also a vulnerability | ||||
| CVE-2019-3826 | 2 Prometheus, Redhat | 3 Prometheus, Openshift, Openshift Container Platform | 2024-11-21 | N/A |
| A stored, DOM based, cross-site scripting (XSS) flaw was found in Prometheus before version 2.7.1. An attacker could exploit this by convincing an authenticated user to visit a crafted URL on a Prometheus server, allowing for the execution and persistent storage of arbitrary scripts. | ||||
