EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.2%, top 35% 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).

Traccar is an open source GPS tracking system. Default installs of Traccar on Windows between versions 6.1- 6.8.1 and non default installs between versions 5.8 - 6.0 are vulnerable to unauthenticated local file inclusion attacks which can lead to leakage of passwords or any file on the file system including the Traccar configuration file. Versions 5.8 - 6.0 are only vulnerable if ./override is set in the configuration file. Versions 6.1 - 6.8.1 are vulnerable by default as the web override is enabled by default. The vulnerable code is removed in version 6.9.0.
