gitlab-exploit skillC
gitlab-exploit is agent-read markdown (skill) from novaestellar/novahaku.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# gitlab-exploit — CVE-2026-85706 GitLab CE/EE unauthenticated arbitrary file read via Workhorse path-encoding bypass. ## Affected Versions - GitLab CE/EE **18.7.0–19.1.7** - GitLab CE/EE **19.2.0–19.2.5** - GitLab CE/EE **19.3.0–19.3.1** **Patched:** 19.1.8 / 19.2.6 / 19.3.2 ## Vulnerability Summary Workhorse regex validates the encoded path; Puma decodes it; Rails `File.open(file.path)` executes **before** authentication check.
