GHSA-jw39-3688-r4rx: compliance-trestle (CVE-2026-54757)

Package	Ecosystem	Affected	Fixed in
compliance-trestle	PyPI	<3.12.4 \|\| >=4.0.0, <4.1.0	3.12.4, 4.1.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Trestle (compliance-trestle) versions before 3.12.4 and from 4.0.0 before 4.1.0 are vulnerable to server-side template injection. The Markdown include tags and the date tag re-parse content as Jinja2 source in an unsandboxed environment. An attacker who can place a crafted Markdown file in the workspace, or supply crafted SSP or LUT data, could run arbitrary commands on the host where trestle renders templates. Upgrade to 3.12.4 or 4.1.0. The source lists no workaround beyond removing the affected tags, auditing included files, and restricting workspace write access.
