It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23892 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- octoprint (PyPI): affected all versions; fixed in 1.11.6\n- octoprint (PyPI): affected all versions; fixed in 1.11.6\n- OctoPrint (PyPI): affected all versions; fixed in 1.11.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-23892/ (Markdown: https://insights.sbomify.com/CVE-2026-23892/index.md)","id":"CVE-2026-23892","markdown":"https://insights.sbomify.com/CVE-2026-23892/index.md","name":"CVE-2026-23892","record":{"aliases":["GHSA-xg4x-w2j3-57h6","PYSEC-2026-1716"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"3D printer control software","requires_auth":"none","summary":"Attackers can potentially extract API keys via timing side-channels in OctoPrint, allowing unauthorized access to 3D printer controls.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"octoprint","vendor":"octoprint"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"OctoPrint provides a web interface for controlling consumer 3D printers. OctoPrint versions up to and including 1.11.5 are affected by a (theoretical) timing attack vulnerability that allows API key extraction over the network. Due to using character based comparison that short-circuits on the first mismatched character during API key validation, rather than a cryptographical method with static runtime regardless of the point of mismatch, an attacker with network based access to an affected OctoPrint could extract API keys valid on the instance by measuring the response times of the denied access responses and guess an API key character by character. The vulnerability is patched in version 1.11.6. The likelihood of this attack actually working is highly dependent on the network's latency, noise and similar parameters. An actual proof of concept was not achieved so far. Still, as always administrators are advised to not expose their OctoPrint instance on hostile networks, especially not on the public Internet.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"OctoPrint has Timing Side-Channel Vulnerability in API Key Authentication","id":"CVE-2026-23892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"openCryptoki has improper link resolution before file access (link following)","id":"CVE-2026-23893"},"packages":[{"ecosystem":"PyPI","fixed":["1.11.6"],"introduced":["0"],"last_affected":[],"package":"OctoPrint","purl":null,"source":"GHSA-xg4x-w2j3-57h6"},{"ecosystem":"PyPI","fixed":["1.11.6"],"introduced":["0"],"last_affected":[],"package":"octoprint","purl":"pkg:pypi/octoprint","source":"GHSA-xg4x-w2j3-57h6"},{"ecosystem":"PyPI","fixed":["1.11.6"],"introduced":["0"],"last_affected":[],"package":"octoprint","purl":"pkg:pypi/octoprint","source":"PYSEC-2026-1716"}],"prev":{"headline":"Decidim has a Cross-site scripting (XSS) vulnerability via user name field","id":"CVE-2026-23891"},"products":["OctoPrint"],"published":"2026-01-27","related":[{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2018-16710","kev_date_added":null,"published":"2018-09-07"},{"cvss_score":7.5,"headline":"OctoPrint is Vulnerable to RCE Attacks via Unsanitized Filename in File Upload","id":"CVE-2025-58180","kev_date_added":null,"published":"2025-09-09"},{"cvss_score":7.5,"headline":"Cross-site Scripting (XSS) - DOM in octoprint/octoprint","id":"CVE-2022-1430","kev_date_added":null,"published":"2022-05-18"},{"cvss_score":7.5,"headline":"Cross-site Scripting (XSS) - Generic in octoprint/octoprint","id":"CVE-2022-1432","kev_date_added":null,"published":"2022-05-18"},{"cvss_score":7.1,"headline":"OctoPrint Authentication Bypass via X-Forwarded-For Header when autologinLocal is enabled","id":"CVE-2024-32977","kev_date_added":null,"published":"2024-05-14"},{"cvss_score":6.5,"headline":"OctoPrint Vulnerable to Denial of Service through malformed HTTP request","id":"CVE-2025-48879","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":6.5,"headline":"OctoPrint Incorrect Access Control","id":"CVE-2021-32560","kev_date_added":null,"published":"2021-05-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-27","vendors":["OctoPrint"]},"summary":"Attackers can potentially extract API keys via timing side-channels in OctoPrint, allowing unauthorized access to 3D printer controls.","url":"https://insights.sbomify.com/CVE-2026-23892/"}
