Description

OctoPrint 1.7.3 and prior does not have rate limiting on the login page, making it possible for attackers to attempt brute force attacks. The severity of this issue is limited by OctoPrint normally running in a restricted LAN. The devel and maintenance branches of the repository have a fix that limits the rate of failed login attempts.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for octoprint, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of octoprint for GHSA-5w5x-q9p5-9qg3. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
