CVE-2026-116815: OpenPanel before 3.0.0 Improper ClickHouse Escaping in sankey.service.ts

MediumCVSS 5.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Openpanel-dev openpanel 3.0.0.

Low priority for now. Upgrade to Openpanel-dev openpanel 3.0.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

OpenPanel before 3.0.0 contains an improper escaping vulnerability in sankey.service.ts that allows authenticated project members to break ClickHouse string literals by supplying backslashes in event names. Attackers with read access can submit crafted events[].name values to the chart.sankey procedure, causing ClickHouse parse errors that disable the project's Sankey chart endpoint.
