It allows locally disabled users to reactivate their accounts just by browsing the affected Jira/Confluence/Bitbucket/Bamboo instance, even when the applicable configuration option of the plugin has been disabled (\"Reactivate inactive users\"). Exploiting this vulnerability requires an attacker to be authorized by the identity provider and requires that the plugin's configuration option \"User Update Method\" have the \"Update from SAML Attributes\" value.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":[],"references":["https://marketplace.atlassian.com/apps/1212129/saml-single-sign-on-sso-confluence?hosting=server&tab=overview","https://wiki.resolution.de/doc/saml-sso/latest/all/security-advisories/2019-07-11-users-are-always-re-enabled-during-login-when-updated","https://marketplace.atlassian.com/apps/1212129/saml-single-sign-on-sso-confluence?hosting=server&tab=overview","https://wiki.resolution.de/doc/saml-sso/latest/all/security-advisories/2019-07-11-users-are-always-re-enabled-during-login-when-updated"],"products":["atlassian:saml_single_sign_on"],"source":"nvd","synced_at":"2026-10-19T20:59:27.069234358+00:00"},"epss":{"cve":"CVE-2019-13347","score":0.01061,"percentile":0.64579,"date":"2026-11-01"},"kev":null,"osv":[],"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).
