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-2026-46721 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- evoweb/sf-register (Packagist): affected all versions; fixed in 13.2.4\n- evoweb/sf-register (Packagist): affected all versions; fixed in 13.2.4\n- evoweb/sf-register (Packagist): affected from 14.0.0; fixed in 14.0.2\n- evoweb/sf-register (Packagist): affected from 14.0.0; fixed in 14.0.2\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-2026-46721/ (Markdown: https://insights.sbomify.com/CVE-2026-46721/index.md)","id":"CVE-2026-46721","markdown":"https://insights.sbomify.com/CVE-2026-46721/index.md","name":"CVE-2026-46721","record":{"aliases":["GHSA-v348-vr4q-fv9p"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 extension","requires_auth":"none","summary":"Attackers can assign arbitrary frontend user groups during registration or editing, gaining unauthorized access to privileged content and functionality.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The create and edit flows do not restrict which user properties may be submitted and do not enforce access control on the frontend user group assignment.
