Verified live against debian:bookworm-slim: apt-cache policy libssh2-1 resolves to candidate 1.10.0-3+b1 from bookworm/main, and the Debian security tracker marks bookworm libssh2 (1.10.0-3) vulnerable with no fixed build in bookworm or bookworm-security (the fix is in trixie-security 1.11.1-1+deb13u1, DSA-6365-1). curl already pulls 1.10.0-3+b1 via libcurl4, so --only-upgrade libssh2-1 re-resolves to that same vulnerable build and changes nothing. This stage does not clear CVE-2026-55200, so the "deterministically clear" comment is not accurate here, and the public plainsightai/openfilter-mcp:latest full image built from this Dockerfile stays exposed. Real options: move this final stage to a trixie base (package becomes libssh2-1t64, fixed at 1.11.1-1+deb13u1, matching Dockerfile and Dockerfile.slim), build or pin a fixed libssh2 from source, or add a Trivy/grype gate that fails the build if the CVE persists.

### Security

- Clear a CRITICAL container-image vulnerability flagged by Security Command Center —
`libssh2` CVE-2026-55200 (CVSS 8.1, exploit available), an OS base-layer package.
Rebuilds on `python:3.12-slim` and **explicitly upgrades `libssh2`** so the fix is
deterministic rather than dependent on the floating base snapshot. Also bumps
`uv.lock` to `0.2.4` so `uv sync --locked` stays reproducible. No application changes.
