An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-32561 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- octoprint (PyPI): affected all versions; fixed in 1.6.0\n- octoprint (PyPI): affected all versions; fixed in 1.6.0\n- OctoPrint (PyPI): affected all versions; fixed in 1.6.0\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-2021-32561/ (Markdown: https://insights.sbomify.com/CVE-2021-32561/index.md)","id":"CVE-2021-32561","markdown":"https://insights.sbomify.com/CVE-2021-32561/index.md","name":"CVE-2021-32561","record":{"aliases":["GHSA-vcx4-fpmp-mvv6","PYSEC-2021-30"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"3D printing server","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in the OctoPrint web interface via reflected XSS in API error messages.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"octoprint","vendor":"octoprint"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"OctoPrint before 1.6.0 allows XSS because API error messages include the values of input parameters.","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 API Error Messages vulnerable to XSS","id":"CVE-2021-32561","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":3,"n_references":3,"next":{"headline":"Code injection in n/a","id":"CVE-2021-32563"},"packages":[{"ecosystem":"PyPI","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"OctoPrint","purl":null,"source":"GHSA-vcx4-fpmp-mvv6"},{"ecosystem":"PyPI","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"octoprint","purl":"pkg:pypi/octoprint","source":"GHSA-vcx4-fpmp-mvv6"},{"ecosystem":"PyPI","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"octoprint","purl":"pkg:pypi/octoprint","source":"PYSEC-2021-30"}],"prev":{"headline":"OctoPrint Incorrect Access Control","id":"CVE-2021-32560"},"products":["n/a"],"published":"2021-05-11","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts in the OctoPrint web interface via reflected XSS in API error messages.","url":"https://insights.sbomify.com/CVE-2021-32561/"}
