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-2026-28352 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- indico (PyPI): affected all versions; fixed in 3.3.11\n- indico (PyPI): affected all versions; fixed in 3.3.11\n- indico (PyPI): affected all versions; fixed in 3.3.11\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-2026-28352/ (Markdown: https://insights.sbomify.com/CVE-2026-28352/index.md)","id":"CVE-2026-28352","markdown":"https://insights.sbomify.com/CVE-2026-28352/index.md","name":"CVE-2026-28352","record":{"aliases":["GHSA-rfpp-2hgm-gp5v","PYSEC-2026-2183"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Indico event management","requires_auth":"none","summary":"Unauthenticated attackers can read, modify, or delete event series metadata in Indico due to a missing access check in the API.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"indico","vendor":"cern"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In versions prior to 3.3.11, the API endpoint used to manage event series is missing an access check, allowing unauthenticated/unauthorized access to this endpoint. The impact of this is limited to getting the metadata (title, category chain, start/end date) for events in an existing series, deleting an existing event series, and modifying an existing event series. This vulnerability does NOT allow unauthorized access to events (beyond the basic metadata mentioned above), nor any kind of tampering with user-visible data in events. Version 3.3.11 fixes the issue. As a workaround, use the webserver to restrict access to the series management API endpoint.","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 missing access check in event series management API","id":"CVE-2026-28352","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Trivy Vulnerability Scanner: Unauthorized AI Agent Execution Code Included in OpenVSX Extension Release","id":"CVE-2026-28353"},"packages":[{"ecosystem":"PyPI","fixed":["3.3.11"],"introduced":["0"],"last_affected":[],"package":"indico","purl":null,"source":"GHSA-rfpp-2hgm-gp5v"},{"ecosystem":"PyPI","fixed":["3.3.11"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"GHSA-rfpp-2hgm-gp5v"},{"ecosystem":"PyPI","fixed":["3.3.11"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"PYSEC-2026-2183"}],"prev":{"headline":"Manipulated RunLengthDecode streams can exhaust RAM","id":"CVE-2026-28351"},"products":["indico"],"published":"2026-02-27","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":7.5,"headline":"Indico Tampering with links (e.g. password reset) in sent emails","id":"CVE-2021-30185","kev_date_added":null,"published":"2021-04-07"},{"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":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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-03","vendors":["indico"]},"summary":"Unauthenticated attackers can read, modify, or delete event series metadata in Indico due to a missing access check in the API.","url":"https://insights.sbomify.com/CVE-2026-28352/"}
