An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18922 in the wild and no public exploit code.\n\nAffected product: Red Hat Directory Server 11.5 E4S for RHEL 8. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-18922/ (Markdown: https://insights.sbomify.com/CVE-2026-18922/index.md)","id":"CVE-2026-18922","markdown":"https://insights.sbomify.com/CVE-2026-18922/index.md","name":"CVE-2026-18922","record":{"aliases":["AZL-99983","DEBIAN-CVE-2026-18922","GHSA-pr87-24g5-hphv","RHSA-2026:64811","UBUNTU-CVE-2026-18922"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"389 Directory Server","requires_auth":"none","summary":"Attackers can escalate privileges to Directory Manager by exploiting stale SASL identity states during authentication sequences.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority without any valid credentials. A variant using a valid low-privileged account's own successful bind instead of an anonymous one is also possible.","ecosystems":["Red Hat:rhel_els:6"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Auth bypass in Red Hat Directory Server 11.5 E4S for RHEL 8","id":"CVE-2026-18922","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":4,"n_references":19,"next":{"headline":"HTTP/2 server push UAF","id":"CVE-2026-18924"},"packages":[{"ecosystem":"Red Hat:rhel_els:6","fixed":["0:1.2.11.15-97.el6_10.1"],"introduced":["0"],"last_affected":[],"package":"389-ds-base","purl":"pkg:rpm/redhat/389-ds-base","source":"RHSA-2026:64811"},{"ecosystem":"Red Hat:rhel_els:6","fixed":["0:1.2.11.15-97.el6_10.1"],"introduced":["0"],"last_affected":[],"package":"389-ds-base-debuginfo","purl":"pkg:rpm/redhat/389-ds-base-debuginfo","source":"RHSA-2026:64811"},{"ecosystem":"Red Hat:rhel_els:6","fixed":["0:1.2.11.15-97.el6_10.1"],"introduced":["0"],"last_affected":[],"package":"389-ds-base-devel","purl":"pkg:rpm/redhat/389-ds-base-devel","source":"RHSA-2026:64811"},{"ecosystem":"Red Hat:rhel_els:6","fixed":["0:1.2.11.15-97.el6_10.1"],"introduced":["0"],"last_affected":[],"package":"389-ds-base-libs","purl":"pkg:rpm/redhat/389-ds-base-libs","source":"RHSA-2026:64811"}],"prev":{"headline":"OAuth 1.0 session-fixation chain via unauthenticated provisional-consumer registration and insecure v1_0Allowed default","id":"CVE-2026-18918"},"products":["Red Hat Directory Server 11.5 E4S for RHEL 8","Red Hat Directory Server 11.7 E4S for RHEL 8","Red Hat Directory Server 11.9 for RHEL 8","Red Hat Directory Server 12","Red Hat Directory Server 12.2 E4S for RHEL 9","Red Hat Directory Server 12.4 E4S for RHEL 9","Red Hat Directory Server 13","Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 10.0 Extended Update Support","Red Hat Enterprise Linux 6 Extended Lifecycle Support  - EXTENSION","Red Hat Enterprise Linux 7 Extended Lifecycle Support","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.8 Telecommunications Update Service","Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.6 Extended Update Support"],"published":"2026-09-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["Red Hat"]},"summary":"Attackers can escalate privileges to Directory Manager by exploiting stale SASL identity states during authentication sequences.","url":"https://insights.sbomify.com/CVE-2026-18922/"}
