GitLab CE/EE unauthenticated arbitrary file read (CVE-2026-85706) via Workhorse path-encoding bypass, with secret extraction and a leaks/oracle-driven verdict. Use when assessing a GitLab instance for the Workhorse encoding bypass, harvesting tokens from readable files, or deciding whether a target is exploitable from its own response.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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. Malformed percent-encoding in multipart upload paths gets interpolated into the HTTP 400 error body → arbitrary file contents leak. **Impact:** Read `/etc/passwd`, `/etc/gitlab/gitlab-secrets.json`, Rails secrets, SSH keys, database credentials, application source code. **CVSS:** 9.1 Critical (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) **Reporter:** s3ntago (HackerOne) **PoC Ref:** `guneykabel/cve-2026-85706` ## Usage ### Single Target ```bash # Auto-detect + loot default secrets python3 testing/gitlab-exploit/gitlab_exploit.py -u https://gitlab.example.com --auto # Read specific file python3 testing/gitlab-exploit/gitlab_exploit.py -u https://gitlab.example.com --file /etc/passwd # Interactive shell …

How to install
mdr add novaestellar/novahaku/gitlab-exploit@sha256:7b65c4c1913f290cThe line at the top of this page pins the label git:20260925.9330cc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
