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-2026-44671 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/zitadel/zitadel (Go): affected all versions; no fix listed\n- github.com/zitadel/zitadel (Go): affected from 2.71.11 up to 2.71.19; no fix listed\n- github.com/zitadel/zitadel (Go): affected from 2.71.11 up to 2.71.19; no fix listed\n- github.com/zitadel/zitadel (Go): affected from 3.1.0; fixed in 3.4.10\n- github.com/zitadel/zitadel (Go): affected from 3.1.0; fixed in 3.4.10\n- github.com/zitadel/zitadel (Go): affected from 4.0.0; fixed in 4.15.0\n- github.com/zitadel/zitadel (Go): affected from 4.0.0; fixed in 4.15.0\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-2026-44671/ (Markdown: https://insights.sbomify.com/CVE-2026-44671/index.md)","id":"CVE-2026-44671","markdown":"https://insights.sbomify.com/CVE-2026-44671/index.md","name":"CVE-2026-44671","record":{"aliases":["GHSA-rxvx-hhpj-q6px","GO-2026-5648"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity management platform","requires_auth":"none","summary":"Unauthenticated attackers can inject LDAP filters to enumerate usernames and extract sensitive directory data via blind injection.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zitadel","vendor":"zitadel"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-90","name":"Improper Neutralization of Special Elements used in an LDAP Query"}],"description":"ZITADEL is an open source identity management platform. From 2.71.11 to before 3.4.10 and 4.15.0, a vulnerability was discovered in Zitadel's LDAP identity provider implementation, which fails to properly escape user-provided usernames before incorporating them into LDAP search filters. This allows unauthenticated attackers to perform LDAP Filter Injection during the login process. While this vulnerability does not allow for a full authentication bypass, an attacker can use LDAP metacharacters (such as *, (, )) to perform blind LDAP injection. By observing the different failure (or success) responses, an attacker can systematically enumerate valid usernames and extract sensitive attribute data from the connected LDAP directory. This vulnerability is fixed in 3.4.10 and 4.15.0.","ecosystems":["Go"],"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":"ZITADEL: LDAP Filter Injection in Login Flow","id":"CVE-2026-44671","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"other","year":"2026"},"n_packages":7,"n_references":3,"next":{"headline":"mapfish-print: Remote Code Injection (RCE) in Dynamic table","id":"CVE-2026-44672"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GO-2026-5648"},{"ecosystem":"Go","fixed":[],"introduced":["2.71.11"],"last_affected":["2.71.19"],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-rxvx-hhpj-q6px"},{"ecosystem":"Go","fixed":[],"introduced":["2.71.11"],"last_affected":["2.71.19"],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-rxvx-hhpj-q6px"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.1.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-rxvx-hhpj-q6px"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.1.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-rxvx-hhpj-q6px"},{"ecosystem":"Go","fixed":["4.15.0"],"introduced":["4.0.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-rxvx-hhpj-q6px"},{"ecosystem":"Go","fixed":["4.15.0"],"introduced":["4.0.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-rxvx-hhpj-q6px"}],"prev":{"headline":"SiYuan: Stored XSS via Attribute View name to Electron renderer RCE in SiYuan","id":"CVE-2026-44670"},"products":["zitadel"],"published":"2026-05-14","related":[{"cvss_score":9.3,"headline":"ZITADEL: 1-Click Account Takeover via XSS in /saml-post Endpoint","id":"CVE-2026-29191","kev_date_added":null,"published":"2026-03-07"},{"cvss_score":9.3,"headline":"ZITADEL Vulnerable to Unauthenticated Full-Read SSRF via V2 Login","id":"CVE-2025-67494","kev_date_added":null,"published":"2025-12-09"},{"cvss_score":9,"headline":"IDOR Vulnerabilities in ZITADEL's Admin API that Primarily Impact LDAP Configurations","id":"CVE-2025-27507","kev_date_added":null,"published":"2025-03-04"},{"cvss_score":8.7,"headline":"Zitadel Bypass Second Authentication Factor","id":"CVE-2025-64103","kev_date_added":null,"published":"2025-10-29"},{"cvss_score":8.7,"headline":"Zitadel Expired JWT Keys Usable for Authorization Grants","id":"CVE-2025-31123","kev_date_added":null,"published":"2025-03-31"},{"cvss_score":8.7,"headline":"ZITADEL Improper Content-Type Validation Leads to Account Takeover via Stored XSS + CSP Bypass","id":"CVE-2024-29891","kev_date_added":null,"published":"2024-03-27"},{"cvss_score":8.7,"headline":"XSS with User Avatar image in ZITADEL","id":"CVE-2023-46238","kev_date_added":null,"published":"2023-10-26"}],"sources":[{"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["zitadel"]},"summary":"Unauthenticated attackers can inject LDAP filters to enumerate usernames and extract sensitive directory data via blind injection.","url":"https://insights.sbomify.com/CVE-2026-44671/"}
