{"apiVersion":"1.0","identifier":"CVE-2026-73644","description":"OpenDJ is an LDAPv3 compliant directory service. Prior to 5.1.2, the SASL PLAIN authorization identity path in opendj-server-legacy/src/main/java/org/opends/server/extensions/PlainSASLMechanismHandler.java checked the PROXIED_AUTH privilege but did not evaluate the mayProxy proxy ACI scope when an authzid resolved to a different user. Both dn: and u: or bare authzid forms could therefore let an authenticated account holding PROXIED_AUTH assume any resolvable non-root identity outside the identities permitted by its proxy ACI. The fix returns INVALID_CREDENTIALS (49) before password verification when the target authorization identity is not permitted. This issue is fixed in version 5.1.2.","publishedAt":"2026-08-13T18:18:20","lastModifiedAt":"2026-08-18T02:17:29","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73644","cvssScore":9.6,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","epssProbability":0.00294,"riskScore":0.99,"affectedProduct":"OpenDJ","affectedVersions":"<5.1.2","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73644","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73644","en":"https://www.redsauce.net/en/cves/CVE-2026-73644","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73644","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73644","de":"https://www.redsauce.net/de/cves/CVE-2026-73644","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73644","el":"https://www.redsauce.net/el/cves/CVE-2026-73644"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73644"}}
