Additionally, users can invite others from the same domain, including administrators, to these events. A standard user can inject an XSS payload into the \"Titre\" and \"Description\" fields when creating an event and then add the administrator or any user to the event. When the invited user (victim) views their own profile, the payload will be executed on their side, even if they do not click on the event.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/toneemarqus/CVE-2024-39031","https://www.github.com/Silverpeas/Silverpeas-Core/pull/1346","https://github.com/toneemarqus/CVE-2024-39031","https://www.github.com/Silverpeas/Silverpeas-Core/pull/1346"],"products":["silverpeas:silverpeas"],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-39031","score":0.00767,"percentile":0.55554,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vfwh-gvf6-mff8","url":"https://osv.dev/vulnerability/GHSA-vfwh-gvf6-mff8","summary":"Silverpeas Core Cross-site Scripting vulnerability","modified":"2025-01-15T15:10:29Z","packages":[{"ecosystem":"Maven","name":"org.silverpeas.core:silverpeas-core-rs","purl":"pkg:maven/org.silverpeas.core/silverpeas-core-rs","ranges":["<=6.3.5"],"fixed":[]},{"ecosystem":"Maven","name":"org.silverpeas.core:silverpeas-core-web","purl":"pkg:maven/org.silverpeas.core/silverpeas-core-web","ranges":["<=6.3.5"],"fixed":[]}]}],"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).
