Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-25739 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- indico (PyPI): affected all versions; fixed in 3.3.10\n- indico (PyPI): affected all versions; fixed in 3.3.10\n- indico (PyPI): affected all versions; fixed in 3.3.10\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-2026-25739/ (Markdown: https://insights.sbomify.com/CVE-2026-25739/index.md)","id":"CVE-2026-25739","markdown":"https://insights.sbomify.com/CVE-2026-25739/index.md","name":"CVE-2026-25739","record":{"aliases":["GHSA-jxc4-54g3-j7vp","PYSEC-2026-2182"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Indico event management","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts via malicious file uploads in Indico, potentially compromising user accounts and session data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"indico","vendor":"cern"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. Versions prior to 3.3.10 are vulnerable to cross-site scripting when uploading certain file types as materials. Users should upgrade to version 3.3.10 to receive a patch. To apply the fix itself updating is sufficient, but to benefit from the strict Content Security Policy (CSP) Indico now applies by default for file downloads, update the webserver config in case one uses nginx with Indico's `STATIC_FILE_METHOD` set to `xaccelredirect`. For further directions, consult the GitHub Security advisory or Indico setup documentation. Some workarounds are available. Use the webserver config to apply a strict CSP for material download endpoints, and/or only let trustworthy users create content (including material uploads, which speakers can typically do as well) on Indico.","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 affected by Cross-Site-Scripting via material uploads","id":"CVE-2026-25739","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Privilege escalation to the `CAP_NET_RAW` capability via the `programs.captive-browser` NixOS module","id":"CVE-2026-25740"},"packages":[{"ecosystem":"PyPI","fixed":["3.3.10"],"introduced":["0"],"last_affected":[],"package":"indico","purl":null,"source":"GHSA-jxc4-54g3-j7vp"},{"ecosystem":"PyPI","fixed":["3.3.10"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"GHSA-jxc4-54g3-j7vp"},{"ecosystem":"PyPI","fixed":["3.3.10"],"introduced":["0"],"last_affected":[],"package":"indico","purl":"pkg:pypi/indico","source":"PYSEC-2026-2182"}],"prev":{"headline":"Indico has Server-Side Request Forgery (SSRF) in multiple places","id":"CVE-2026-25738"},"products":["indico"],"published":"2026-02-19","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":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":"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-19","vendors":["indico"]},"summary":"Attackers can execute arbitrary scripts via malicious file uploads in Indico, potentially compromising user accounts and session data.","url":"https://insights.sbomify.com/CVE-2026-25739/"}
