An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-36962 exists.\n\nAffected packages and fixed versions:\n- tendenci (PyPI): affected all versions up to 12.3.1; no fix listed\n- tendenci (PyPI): affected all versions; fixed in 12.3.2\n- tendenci (PyPI): affected all versions; fixed in 12.3.2\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-2020-36962/ (Markdown: https://insights.sbomify.com/CVE-2020-36962/index.md)","id":"CVE-2020-36962","markdown":"https://insights.sbomify.com/CVE-2020-36962/index.md","name":"CVE-2020-36962","record":{"aliases":["GHSA-4q3w-jgfx-4792","PYSEC-2026-136"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Tendenci CMS","requires_auth":"none","summary":"Attackers can inject malicious formulas into contact form messages, leading to arbitrary command execution when the exported CSV is opened in spreadsheet software.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"tendenci","vendor":"tendenci"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"Tendenci 12.3.1 contains a CSV formula injection vulnerability in the contact form message field that allows attackers to inject malicious formulas during export.
