Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55770 exists.\n\nAffected packages and fixed versions:\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617104213-10b7825c714c\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617104213-10b7825c714c\n- github.com/openbao/openbao (Go): affected all versions; fixed in 0.0.0-20260617104213-10b7825c714c\n- github.com/openbao/openbao (Go): affected from 0.1.0 up to 2.5.4; no fix listed\n- github.com/openbao/openbao (Go): affected from 0.1.0 up to 2.5.4; no fix listed\n- openbao (Bitnami): affected all versions; fixed in 2.5.5\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-2026-55770/ (Markdown: https://insights.sbomify.com/CVE-2026-55770/index.md)","id":"CVE-2026-55770","markdown":"https://insights.sbomify.com/CVE-2026-55770/index.md","name":"CVE-2026-55770","record":{"aliases":["BIT-openbao-2026-55770","GHSA-6mwx-4547-5vc9","GO-2026-5182"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenBao secrets manager","requires_auth":"low_privilege","summary":"Attackers can bypass LDAP authentication filters to impersonate other users and access their secrets if specific AD binding configurations are enabled.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-90","name":"Improper Neutralization of Special Elements used in an LDAP Query"}],"description":"OpenBao is an open source identity-based secrets management system. Prior to 2.5.5, OpenBao used EscapeLDAPValue, an RFC 4514 distinguished-name escaping function, where RFC 4515 LDAP search-filter escaping was required in sdk/helper/ldaputil/client.go GetUserDN. With the LDAP authentication backend configured for an Active Directory UPNDomain path or UserDN and UserAttr binding, an attacker-controlled username containing filter metacharacters could alter the search predicate and select a different directory entry because EscapeLDAPValue does not neutralize the characters handled by ldap.EscapeFilter. A resulting token could be associated with another LDAP identity and gain access to secrets, policies, or modification capabilities assigned to that identity. This issue is fixed in version 2.5.5.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"OpenBao: LDAPi ldaputil (wrong escape func)","id":"CVE-2026-55770","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"other","year":"2026"},"n_packages":6,"n_references":7,"next":{"headline":"CedarJava has policy injection, type confusion, and incorrect equality comparison vulnerabilities","id":"CVE-2026-55771"},"packages":[{"ecosystem":"Bitnami","fixed":["2.5.5"],"introduced":["0"],"last_affected":[],"package":"openbao","purl":"pkg:bitnami/openbao","source":"BIT-openbao-2026-55770"},{"ecosystem":"Go","fixed":["0.0.0-20260617104213-10b7825c714c"],"introduced":["0","0.1.0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GO-2026-5182"},{"ecosystem":"Go","fixed":["0.0.0-20260617104213-10b7825c714c"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-6mwx-4547-5vc9"},{"ecosystem":"Go","fixed":["0.0.0-20260617104213-10b7825c714c"],"introduced":["0"],"last_affected":[],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-6mwx-4547-5vc9"},{"ecosystem":"Go","fixed":[],"introduced":["0.1.0"],"last_affected":["2.5.4"],"package":"github.com/openbao/openbao","purl":null,"source":"GHSA-6mwx-4547-5vc9"},{"ecosystem":"Go","fixed":[],"introduced":["0.1.0"],"last_affected":["2.5.4"],"package":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","source":"GHSA-6mwx-4547-5vc9"}],"prev":{"headline":"Privilege escalation in cloudnative-pg","id":"CVE-2026-55769"},"products":["openbao"],"published":"2026-09-15","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["openbao"]},"summary":"Attackers can bypass LDAP authentication filters to impersonate other users and access their secrets if specific AD binding configurations are enabled.","url":"https://insights.sbomify.com/CVE-2026-55770/"}
