An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-5600 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pretix (PyPI): affected from 2025.10.0; fixed in 2026.1.2, 2026.2.1, 2026.3.1\n- pretix (PyPI): affected from 2025.10.0; fixed in 2026.1.2\n- pretix (PyPI): affected from 2025.10.0; fixed in 2026.1.2\n- pretix (PyPI): affected from 2026.2.0; fixed in 2026.2.1\n- pretix (PyPI): affected from 2026.2.0; fixed in 2026.2.1\n- pretix (PyPI): affected from 2026.3.0; fixed in 2026.3.1\n- pretix (PyPI): affected from 2026.3.0; fixed in 2026.3.1\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-2026-5600/ (Markdown: https://insights.sbomify.com/CVE-2026-5600/index.md)","id":"CVE-2026-5600","markdown":"https://insights.sbomify.com/CVE-2026-5600/index.md","name":"CVE-2026-5600","record":{"aliases":["GHSA-wr8q-c73g-m7gp","PYSEC-2026-111"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Event ticketing platform","requires_auth":"high_privilege","summary":"An API flaw in pretix allows unauthorized users to view check-in data for all events under an organizer, exposing ticket scan details.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rami.io","cpe":[{"product":"pretix","vendor":"pretix"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-653","name":"Improper Isolation or Compartmentalization"}],"description":"A new API endpoint introduced in pretix 2025 that is supposed to \nreturn all check-in events of a specific event in fact returns all \ncheck-in events belonging to the respective organizer.
