Lektor before 3.3.11 does not sanitize DB path traversal. Thus, shell commands might be executed via a file that is added to the templates directory, if the victim's web browser accesses an untrusted website that uses JavaScript to send requests to localhost port 5000, and the web browser is running on the same machine as the "lektor server" command.
CVE-2024-28335
This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 0.8%, top 46% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
