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-2026-28696 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- craftcms/cms (Packagist): affected from 4.0.0-RC1; fixed in 4.17.0-beta.1\n- craftcms/cms (Packagist): affected from 4.0.0-RC1; fixed in 4.17.0-beta.1\n- craftcms/cms (Packagist): affected from 5.0.0-RC1; fixed in 5.9.0-beta.1\n- craftcms/cms (Packagist): affected from 5.0.0-RC1; fixed in 5.9.0-beta.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-2026-28696/ (Markdown: https://insights.sbomify.com/CVE-2026-28696/index.md)","id":"CVE-2026-28696","markdown":"https://insights.sbomify.com/CVE-2026-28696/index.md","name":"CVE-2026-28696","record":{"aliases":["GHSA-7x43-mpfg-r9wj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS","requires_auth":"none","summary":"Attackers can read sensitive data from any CMS element via GraphQL @parseRefs due to missing authorization checks in Craft CMS.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"craft_cms","vendor":"craftcms"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Craft is a content management system (CMS). Prior to 4.17.0-beta.1 and 5.9.0-beta.1, the GraphQL directive @parseRefs, intended to parse internal reference tags (e.g., {user:1:email}), can be abused by both authenticated users and unauthenticated guests (if a Public Schema is enabled) to access sensitive attributes of any element in the CMS. The implementation in Elements::parseRefs fails to perform authorization checks, allowing attackers to read data they are not authorized to view.
