Prior to 3.3.13, an authenticated user can misuse the legacy session export API to retrieve details for a restricted session without access to that session, as long as the containing event is accessible. The missing access check can disclose session metadata such as the title, description, and conveners. This issue is fixed in version 3.3.13.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://github.com/indico/indico/commit/524e8e93eadcd8484905b1147020a35f5dce6038","https://github.com/indico/indico/releases/tag/v3.3.13","https://github.com/indico/indico/security/advisories/GHSA-6p4f-j8j6-463q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107395","score":0.00235,"percentile":0.14242,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6p4f-j8j6-463q","url":"https://osv.dev/vulnerability/GHSA-6p4f-j8j6-463q","summary":"Indico: Missing access check in legacy session export API","modified":"2026-10-15T14:55:57.961569407Z","packages":[{"ecosystem":"PyPI","name":"indico","purl":"pkg:pypi/indico","ranges":["<3.3.13"],"fixed":["3.3.13"]}]},{"id":"PYSEC-2026-4226","url":"https://osv.dev/vulnerability/PYSEC-2026-4226","summary":"Indico: Missing access check in legacy session export API","modified":"2026-10-15T14:45:04.405874866Z","packages":[{"ecosystem":"PyPI","name":"indico","purl":"pkg:pypi/indico","ranges":["<3.3.13"],"fixed":["3.3.13"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
