It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-40848 and fix it if it is affected.\n\nWhat it is: CVE-2021-40848 is a high-severity code injection vulnerability in Mahara Mahara, published on 3 Nov 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-40848 in the wild and no public exploit code.\n\nAffected product: Mahara Mahara. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-40848/ (Markdown: https://insights.sbomify.com/CVE-2021-40848/index.md)","id":"CVE-2021-40848","markdown":"https://insights.sbomify.com/CVE-2021-40848/index.md","name":"CVE-2021-40848","record":{"aliases":["GHSA-xxj6-2w57-fchv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mahara ePortfolio","requires_auth":"none","summary":"Attackers can inject malicious formulas into exported CSV files, leading to local code execution when opened in spreadsheet software.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mahara","vendor":"mahara"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"In Mahara before 20.04.5, 20.10.3, 21.04.2, and 21.10.0, exported CSV files could contain characters that a spreadsheet program could interpret as a command, leading to execution of a malicious string locally on a device, aka CSV injection.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Code injection in n/a","id":"CVE-2021-40848","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mahara:mahara","products":["mahara:mahara"],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in n/a","id":"CVE-2021-40849"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2021-40847"},"products":["n/a"],"published":"2021-11-03","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2022-45134","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-44544","kev_date_added":null,"published":"2022-11-06"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-40849","kev_date_added":null,"published":"2021-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000152","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000153","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000154","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2024-39335","kev_date_added":null,"published":"2025-08-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject malicious formulas into exported CSV files, leading to local code execution when opened in spreadsheet software.","url":"https://insights.sbomify.com/CVE-2021-40848/"}
