CVE-2024-32977 has a CVSS score of 7.1/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-32977?

CVE-2024-32977 affects the following packages: octoprint (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2024-32977?

Update octoprint to 1.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-32977 is resolved across your whole dependency graph.

How do I detect CVE-2024-32977 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for octoprint. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-32977 if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against CVE-2024-32977?

O3 pinpoints whether CVE-2024-32977 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-32977 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-32977 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-32977?

CVE-2024-32977 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 55th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-32977?

CVE-2024-32977 is classified as CWE-290 (CWE-290). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-32977 published, and has it been updated?

CVE-2024-32977 was published on May 14, 2024 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

OctoPrint provides a web interface for controlling consumer 3D printers. OctoPrint versions up until and including 1.10.0 contain a vulnerability that allows an unauthenticated attacker to completely bypass the authentication if the autologinLocal option is enabled within config.yaml, even if they come from networks that are not configured as localNetworks, spoofing their IP via the X-Forwarded-For header. If autologin is not enabled, this vulnerability does not have any impact. The vulnerability has been patched in version 1.10.1. Until the patch has been applied, OctoPrint administrators who have autologin enabled on their instances should disable it and/or to make the instance inaccessible from potentially hostile networks like the internet.
