Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-29134 in the wild and no public exploit code.\n\nAffected product: SEPPmail Secure Email Gateway. 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-2026-29134/ (Markdown: https://insights.sbomify.com/CVE-2026-29134/index.md)","id":"CVE-2026-29134","markdown":"https://insights.sbomify.com/CVE-2026-29134/index.md","name":"CVE-2026-29134","record":{"aliases":["GHSA-v5jf-vjfx-frfr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Secure Email Gateway","requires_auth":"low_privilege","summary":"An external attacker can modify GINA webdomain metadata to bypass per-domain restrictions in SEPPmail Secure Email Gateway.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[{"product":"secure_email_gateway","vendor":"seppmail"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-807","name":"Reliance on Untrusted Inputs in a Security Decision"}],"description":"SEPPmail Secure Email Gateway before version 15.0.3 allows an external user to modify GINA webdomain metadata and bypass per-domain restrictions.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"GINA Domain Switch","id":"CVE-2026-29134","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Webmail Password Tag Sanitization Bypass","id":"CVE-2026-29135"},"packages":[],"prev":{"headline":"UID Regex Bypass","id":"CVE-2026-29133"},"products":["Secure Email Gateway"],"published":"2026-04-02","related":[{"cvss_score":7.8,"headline":"GINA State Confusion Account Takeover","id":"CVE-2026-29139","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.8,"headline":"S/MIME Decryption Impersonation","id":"CVE-2026-29143","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.8,"headline":"Unicode Subject Tags","id":"CVE-2026-29144","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.7,"headline":"S/MIME Signature Additional Certificate","id":"CVE-2026-29140","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.7,"headline":"Bounded Subject Tag Sanitization","id":"CVE-2026-29141","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":6.3,"headline":"ESWmail-Verify Bypass","id":"CVE-2026-29132","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":6.3,"headline":"PGP Decryption Sender LDAP Injection","id":"CVE-2026-29138","kev_date_added":null,"published":"2026-04-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-02","vendors":["SEPPmail"]},"summary":"An external attacker can modify GINA webdomain metadata to bypass per-domain restrictions in SEPPmail Secure Email Gateway.","url":"https://insights.sbomify.com/CVE-2026-29134/"}
