CVE-2023-2183
MEDIUMCVE-2023-2183 is a medium-severity (CVSS 4.1) CWE-284 vulnerability in github.com/grafana/grafana. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2023-2183 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Grafana has Broken Access Control in Alert manager: Viewer can send test alerts

github.com/grafana/grafana🐹github.com/grafana/grafana🐹github.com/grafana/grafana🐹github.com/grafana/grafana🐹github.com/grafana/grafanaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Grafana is an open-source platform for monitoring and observability.
The option to send a test alert is not available from the user panel UI for users having the Viewer role. It is still possible for a user with the Viewer role to send a test alert using the API as the API does not check access to this function.
This might enable malicious users to abuse the functionality by sending multiple alert messages to e-mail and Slack, spamming users, prepare Phishing attack or block SMTP server.
Users may upgrade to version 9.5.3, 9.4.12, 9.3.15, 9.2.19 and 8.5.26 to receive a fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/grafana/grafana. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/grafana/grafana to 8.5.26 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-2183 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-2183 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-2183. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
