An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-30185 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- indico (PyPI): affected all versions; fixed in 2.3.4\n- indico (PyPI): affected all versions; fixed in 2.3.4\n- indico (PyPI): affected all versions; fixed in 2.3.4\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-2021-30185/ (Markdown: https://insights.sbomify.com/CVE-2021-30185/index.md)","id":"CVE-2021-30185","markdown":"https://insights.sbomify.com/CVE-2021-30185/index.md","name":"CVE-2021-30185","record":{"aliases":["GHSA-wgpj-7c2j-vfjm","PYSEC-2021-18"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Indico event management","requires_auth":"none","summary":"Attackers can manipulate the Host header in password reset links to redirect users to malicious sites, potentially leading to account takeover.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"indico","vendor":"cern"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"CERN Indico before 2.3.4 can use an attacker-supplied Host header in a password reset link.","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":"Indico Tampering with links (e.g. password reset) in sent emails","id":"CVE-2021-30185","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"open_redirect","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-30186"},"packages":[{"ecosystem":"PyPI","fixed":["2.3.4"],"introduced":["0"],"last_affected":[],"package":"indico","purl":null,"source":"GHSA-wgpj-7c2j-vfjm"},{"ecosystem":"PyPI","fixed":["2.3.4"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"GHSA-wgpj-7c2j-vfjm"},{"ecosystem":"PyPI","fixed":["2.3.4"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"PYSEC-2021-18"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-30184"},"products":["n/a"],"published":"2021-04-07","related":[{"cvss_score":7.7,"headline":"Indico discloses local files resulting in Remote Code Execution through LaTeX injection","id":"CVE-2026-33046","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":6.9,"headline":"Indico has Server-Side Request Forgery (SSRF) in multiple places","id":"CVE-2026-25738","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":6.5,"headline":"Indico missing access check in event series management API","id":"CVE-2026-28352","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":5.4,"headline":"Indico affected by Cross-Site-Scripting via material uploads","id":"CVE-2026-25739","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":5.4,"headline":"Cross-Site-Scripting via confirmation prompts","id":"CVE-2023-37901","kev_date_added":null,"published":"2023-07-21"},{"cvss_score":5.3,"headline":"Indico vulnerable to user enumeration via API endpoint","id":"CVE-2025-53640","kev_date_added":null,"published":"2025-07-14"}],"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":"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 manipulate the Host header in password reset links to redirect users to malicious sites, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2021-30185/"}
