Authentication bypass in Grafana OnCall through 1.16.11 lets unauthenticated remote attackers mint a valid PluginAuthToken by POSTing to the internal plugin install endpoint with hardcoded default stack_id and org_id values exposed in the public source tree, then use that token to seize full control of the OnCall instance. With the token, an attacker can create arbitrary Admin users via the user-context header bootstrap path, revoke the legitimate plugin token to lock out operators, and redirect OnCall-to-Grafana API traffic to an attacker host by overwriting grafana_url and api_token. Publicly available exploit code exists (reported by VulnCheck), CVSS 4.0 base 9.3, though there is no public exploit identified as actively exploited - it is not on CISA KEV.
Grafana OnCall is an easy-to-use on-call management tool that will help reduce toil in on-call management through simpler workflows and interfaces that are tailored specifically for engineers. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
LinkedIn Oncall through 1.4.0 allows reflected XSS via /query because of mishandling of the "No results found for" message in the search bar. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
