Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-28782 exists.\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-2026-28782/ (Markdown: https://insights.sbomify.com/CVE-2026-28782/index.md)","id":"CVE-2026-28782","markdown":"https://insights.sbomify.com/CVE-2026-28782/index.md","name":"CVE-2026-28782","record":{"aliases":["GHSA-jxm3-pmm2-9gf6"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS","requires_auth":"low_privilege","summary":"Attackers can bypass permissions to duplicate other users' entries via IDOR, leading to unauthorized data access and modification 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":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/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 5.9.0-beta.1 and 4.17.0-beta.1, the \"Duplicate\" entry action does not properly verify if the user has permission to perform this action on the specific target elements. Even with only \"View Entries\" permission (where the \"Duplicate\" action is restricted in the UI), a user can bypass this restriction by sending a direct request. Furthermore, this vulnerability allows duplicating other users' entries by specifying their Entry IDs. Since Entry IDs are incremental, an attacker can trivially brute-force these IDs to duplicate and access restricted content across the system. This vulnerability is fixed in 5.9.0-beta.1 and 4.17.0-beta.1.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Craft has a Permission Bypass and IDOR in Duplicate Entry Action","id":"CVE-2026-28782","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"craftcms:craft_cms","products":["craftcms:craft_cms"],"type":"missing_authorization","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Craft has a Twig Function Blocklist Bypass","id":"CVE-2026-28783"},"packages":[{"ecosystem":"Packagist","fixed":["4.17.0-beta.1"],"introduced":["4.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":null,"source":"GHSA-jxm3-pmm2-9gf6"},{"ecosystem":"Packagist","fixed":["4.17.0-beta.1"],"introduced":["4.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":"pkg:composer/craftcms/cms","source":"GHSA-jxm3-pmm2-9gf6"},{"ecosystem":"Packagist","fixed":["5.9.0-beta.1"],"introduced":["5.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":null,"source":"GHSA-jxm3-pmm2-9gf6"},{"ecosystem":"Packagist","fixed":["5.9.0-beta.1"],"introduced":["5.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":"pkg:composer/craftcms/cms","source":"GHSA-jxm3-pmm2-9gf6"}],"prev":{"headline":"Craft Affected by Entries Authorship Spoofing via Mass Assignment","id":"CVE-2026-28781"},"products":["cms"],"published":"2026-03-04","related":[{"cvss_score":10,"headline":"Craft CMS Code Injection","id":"CVE-2025-32432","kev_date_added":"2026-03-20","published":"2025-04-25"},{"cvss_score":9.3,"headline":"Craft CMS Code Injection","id":"CVE-2024-56145","kev_date_added":"2025-06-02","published":"2024-12-18"},{"cvss_score":8.1,"headline":"Craft CMS Code Injection","id":"CVE-2025-23209","kev_date_added":"2025-02-20","published":"2025-01-18"},{"cvss_score":6.9,"headline":"Craft CMS External Control of Assumed-Immutable Web Parameter","id":"CVE-2025-35939","kev_date_added":"2025-06-02","published":"2025-05-07"},{"cvss_score":10,"headline":"Craft CMS Remote Code Execution vulnerability","id":"CVE-2023-41892","kev_date_added":null,"published":"2023-09-13"},{"cvss_score":9.8,"headline":"Craft CMS Remote Code Injection","id":"CVE-2021-27903","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":9.8,"headline":"SEOmatic for CraftCMS allows Server-Side Template Injection","id":"CVE-2020-9757","kev_date_added":null,"published":"2020-03-04"}],"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":"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-04","vendors":["craftcms"]},"summary":"Attackers can bypass permissions to duplicate other users' entries via IDOR, leading to unauthorized data access and modification in Craft CMS.","url":"https://insights.sbomify.com/CVE-2026-28782/"}
