Shiro Affected by an Observable Timing Discrepancy Vulnerability\nObservable Timing Discrepancy vulnerability in Apache Shiro.\n\nThis issue affects Apache Shiro: from 1.*, 2.* before 2.0.7.\n\nUsers are recommended to upgrade to version 2.0.7 or later, which fixes the issue.\n\nPrior to Shiro 2.0.7, code paths for non-existent vs. existing users are different enough,\nthat a brute-force attack may be able to tell, by timing the requests only, determine if\nthe request failed because of a non-existent user vs. wrong password.\n\nThe most likely attack vector is a local attack only.\nShiro security model  https://shiro.apache.org/security-model.html#username_enumeration  discusses this as well.\n\nTypically, brute force attack can be mitigated at the infrastructure level.","references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2026-23901.json","reference_id":"","reference_type":"","scores":[{"value":"2.9","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2026-23901.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-23901","reference_id":"","reference_type":"","scores":[{"value":"9e-05","scoring_system":"epss","scoring_elements":"0.00947","published_at":"2026-06-07T12:55:00Z"},{"value":"9e-05","scoring_system":"epss","scoring_elements":"0.00946","published_at":"2026-06-05T12:55:00Z"},{"value":"9e-05","scoring_system":"epss","scoring_elements":"0.00945","published_at":"2026-06-08T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-23901"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-23901","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-23901"},{"reference_url":"https://github.com/apache/shiro","reference_id":"","reference_type":"","scores":[{"value":"1.0","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/apache/shiro"},{"reference_url":"https://lists.apache.org/thread/mm1jct9b86jvnh3y44tj22xvjtx3xhhh","reference_id":"","reference_type":"","scores":[{"value":"1","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/S:N/AU:Y/R:A/V:C/RE:L/U:Green"},{"value":"1.0","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-02-10T15:31:09Z/"}],"url":"https://lists.apache.org/thread/mm1jct9b86jvnh3y44tj22xvjtx3xhhh"},{"reference_url":"http://www.openwall.com/lists/oss-security/2026/02/08/2","reference_id":"","reference_type":"","scores":[{"value":"1.0","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"http://www.openwall.com/lists/oss-security/2026/02/08/2"},{"reference_url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1127944","reference_id":"1127944","reference_type":"","scores":[],"url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1127944"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2438436","reference_id":"2438436","reference_type":"","scores":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2438436"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23901","reference_id":"CVE-2026-23901","reference_type":"","scores":[{"value":"1.0","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23901"},{"reference_url":"https://github.com/advisories/GHSA-c4qc-4q9p-m9q9","reference_id":"GHSA-c4qc-4q9p-m9q9","reference_type":"","scores":[{"value":"LOW","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-c4qc-4q9p-m9q9"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/73968?format=json","purl":"pkg:maven/org.apache.shiro/shiro-core@2.1.0","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.apache.shiro/shiro-core@2.1.0"}],"aliases":["CVE-2026-23901","GHSA-c4qc-4q9p-m9q9"],"risk_score":1.4,"exploitability":"0.5","weighted_severity":"2.7","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-cxgu-m7wr-1ydv"}],"fixing_vulnerabilities":[],"risk_score":"1.4","resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.apache.shiro/shiro-core@2.0.0"}
