An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-27946 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/zitadel/zitadel (Go): affected all versions; fixed in 1.80.0-v2.20.0.20260225053417-0261536243e5\n- github.com/zitadel/zitadel (Go): affected all versions; fixed in 1.80.0-v2.20.0.20260225053417-0261536243e5\n- github.com/zitadel/zitadel (Go): affected all versions; fixed in 1.80.0-v2.20.0.20260225053417-0261536243e5\n- github.com/zitadel/zitadel (Go): affected from 2.43.0; fixed in 3.4.7\n- github.com/zitadel/zitadel (Go): affected from 2.43.0; fixed in 3.4.7\n- github.com/zitadel/zitadel (Go): affected from 4.0.0; fixed in 4.11.1\n- github.com/zitadel/zitadel (Go): affected from 4.0.0; fixed in 4.11.1\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-2026-27946/ (Markdown: https://insights.sbomify.com/CVE-2026-27946/index.md)","id":"CVE-2026-27946","markdown":"https://insights.sbomify.com/CVE-2026-27946/index.md","name":"CVE-2026-27946","record":{"aliases":["GHSA-282g-fhmx-xf54","GO-2026-4572"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity management platform","requires_auth":"none","summary":"Attackers can bypass email and phone verification checks in ZITADEL by self-verifying their contact details via the API.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zitadel","vendor":"zitadel"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"ZITADEL is an open source identity management platform.

The patch in versions 4.11.1 and 3.4.7 resolves the issue by requiring the correct permission in case the verification flag is provided and only allows self-management of the email address and/or phone number itself. If an upgrade is not possible, an action (v2) could be used to prevent setting the verification flag on the own user.","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 Users Can Self-Verify Email/Phone via UpdateHumanUser API","id":"CVE-2026-27946","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":7,"n_references":1,"next":{"headline":"Group-Office Vulnerable to Remote Code Execution (RCE)","id":"CVE-2026-27947"},"packages":[{"ecosystem":"Go","fixed":["1.80.0-v2.20.0.20260225053417-0261536243e5"],"introduced":["0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-282g-fhmx-xf54"},{"ecosystem":"Go","fixed":["1.80.0-v2.20.0.20260225053417-0261536243e5"],"introduced":["0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-282g-fhmx-xf54"},{"ecosystem":"Go","fixed":["1.80.0-v2.20.0.20260225053417-0261536243e5"],"introduced":["0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GO-2026-4572"},{"ecosystem":"Go","fixed":["3.4.7"],"introduced":["2.43.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-282g-fhmx-xf54"},{"ecosystem":"Go","fixed":["3.4.7"],"introduced":["2.43.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-282g-fhmx-xf54"},{"ecosystem":"Go","fixed":["4.11.1"],"introduced":["4.0.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":null,"source":"GHSA-282g-fhmx-xf54"},{"ecosystem":"Go","fixed":["4.11.1"],"introduced":["4.0.0"],"last_affected":[],"package":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","source":"GHSA-282g-fhmx-xf54"}],"prev":{"headline":"ZITADEL has potential SSRF via Actions","id":"CVE-2026-27945"},"products":["zitadel"],"published":"2026-02-26","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":"2026-02-26","vendors":["zitadel"]},"summary":"Attackers can bypass email and phone verification checks in ZITADEL by self-verifying their contact details via the API.","url":"https://insights.sbomify.com/CVE-2026-27946/"}
