CVE-2026-34228: Emlog: CSRF in Backend Upgrade Interface Leading to Arbitrary Remote SQL Execution and Arbitrary File Write

Noroxi assessment

Priority: Monitor (action score 34/100)

  • 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: 0.19% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: emlog emlog 2.6.8.

Low priority for now. Upgrade to emlog emlog 2.6.8 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.
