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-2026-55634 exists.\n\nAffected packages and fixed versions:\n- pimcore/pimcore (Packagist): affected all versions; fixed in 12.3.10\n- pimcore/pimcore (Packagist): affected all versions; fixed in 12.3.10\n- pimcore/pimcore (Packagist): affected from 2026.1.0; fixed in 2026.1.6\n- pimcore/pimcore (Packagist): affected from 2026.1.0; fixed in 2026.1.6\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-2026-55634/ (Markdown: https://insights.sbomify.com/CVE-2026-55634/index.md)","id":"CVE-2026-55634","markdown":"https://insights.sbomify.com/CVE-2026-55634/index.md","name":"CVE-2026-55634","record":{"aliases":["GHSA-9x44-4gxf-8c25"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Pimcore DXP platform","requires_auth":"low_privilege","summary":"Authenticated users can inject PHP code and SQL identifiers via DataObject field names, leading to remote code execution and schema modification.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"Pimcore is an Open Source Data \u0026 Experience Management Platform. Prior to 11.5.19, 12.3.10, and 2026.1.6, the class-definition import endpoint /pimcore-studio/api/class/definition/configuration-view/detail/{id}/import accepts a DataObject field name that is emitted without an identifier allowlist by lib/DataObject/ClassBuilder/FieldDefinitionPropertiesBuilder.php into generated PHP properties and by models/DataObject/ClassDefinition/Helper/Dao.php into ALTER TABLE identifiers. An authenticated user with the objects permission can inject PHP syntax into the generated DataObject class, causing attacker-controlled code in generated var/classes/DataObject/.php files to run when an object of that class is instantiated, and can also inject SQL identifier content into schema-changing statements. The central models/DataObject/ClassDefinition/Data.php::setName() validation did not reject semicolons, braces, backticks, spaces, or other non-identifier characters. This issue is fixed in versions 11.5.19, 12.3.10, and 2026.1.6.","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":"Pimcore: Remote Code Execution via DataObject Class-Definition Field Name","id":"CVE-2026-55634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":4,"n_references":5,"next":{"headline":"DataEase: Authenticated SQL Injection in Chart Quota Filters","id":"CVE-2026-55635"},"packages":[{"ecosystem":"Packagist","fixed":["12.3.10"],"introduced":["0"],"last_affected":[],"package":"pimcore/pimcore","purl":null,"source":"GHSA-9x44-4gxf-8c25"},{"ecosystem":"Packagist","fixed":["12.3.10"],"introduced":["0"],"last_affected":[],"package":"pimcore/pimcore","purl":"pkg:composer/pimcore/pimcore","source":"GHSA-9x44-4gxf-8c25"},{"ecosystem":"Packagist","fixed":["2026.1.6"],"introduced":["2026.1.0"],"last_affected":[],"package":"pimcore/pimcore","purl":null,"source":"GHSA-9x44-4gxf-8c25"},{"ecosystem":"Packagist","fixed":["2026.1.6"],"introduced":["2026.1.0"],"last_affected":[],"package":"pimcore/pimcore","purl":"pkg:composer/pimcore/pimcore","source":"GHSA-9x44-4gxf-8c25"}],"prev":{"headline":"DataEase H2 RCE via Zip Protocol \u0026 File Dropper Fix bypass","id":"CVE-2026-55633"},"products":["pimcore"],"published":"2026-08-28","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["pimcore"]},"summary":"Authenticated users can inject PHP code and SQL identifiers via DataObject field names, leading to remote code execution and schema modification.","url":"https://insights.sbomify.com/CVE-2026-55634/"}
