Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104733 in the wild and no public exploit code.\n\nAffected product: ProcessOne ejabberd. 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-2026-104733/ (Markdown: https://insights.sbomify.com/CVE-2026-104733/index.md)","id":"CVE-2026-104733","markdown":"https://insights.sbomify.com/CVE-2026-104733/index.md","name":"CVE-2026-104733","record":{"aliases":["DEBIAN-CVE-2026-104733","GHSA-339c-8fr4-g2w4","UBUNTU-CVE-2026-104733"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"XMPP server","requires_auth":"low_privilege","summary":"Attackers can impersonate arbitrary users in ejabberd by exploiting an unvalidated authzid parameter in the SASL-PLAIN mechanism.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"User Impersonation in ProcessOnes XMMP Server ejabberd \u003c= 26.04 allows an attacker to impersonate arbitrary users via unvalidated authzid parameter in SASL-PLAIN mechanism.","ecosystems":[],"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":"User Impersonation/Authorization Bypass in XMPP Server ejabberd","id":"CVE-2026-104733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Deserialization in Kirki – Freeform Page Builder, Website Builder \u0026 Customizer","id":"CVE-2026-104734"},"packages":[],"prev":{"headline":"Advanced IP Blocker \u003c= 8.13.13 - Unauthenticated Authentication Bypass via Missing Step-1 Binding to 2FA Login Handler","id":"CVE-2026-104732"},"products":["ejabberd"],"published":"2026-10-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-02","vendors":["ProcessOne"]},"summary":"Attackers can impersonate arbitrary users in ejabberd by exploiting an unvalidated authzid parameter in the SASL-PLAIN mechanism.","url":"https://insights.sbomify.com/CVE-2026-104733/"}
