HIGHPre-NVD 7.87.8—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 93% 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).

compliance-trestle is a tooling platform for managing compliance as code. Versions prior to 3.12.2 and 4.0.3 have a Server-Side Template Injection (SSTI) vulnerability exists in the trestle author jinja command. The command recursively evaluates rendered templates, allowing an attacker to achieve arbitrary command execution with privileges of the running process by injecting malicious payloads into data fields (such as SSP documents or Lookup Tables). The vulnerability does not require attacker control of the template itself. Only attacker-controlled input data rendered into a trusted template is required. This distinction is critical: the template author may only intend to render plain text (e.g., Title: {{ ssp.metadata.title }}), but because of the recursive parsing, the data field itself becomes executable. The vulnerability is caused by recursive re-compilation and re-rendering of already-rendered output. Versions 3.12.3 and 4.0.3 patch the issue.
