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-2026-55220 in the wild and no public exploit code.\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-2026-55220/ (Markdown: https://insights.sbomify.com/CVE-2026-55220/index.md)","id":"CVE-2026-55220","markdown":"https://insights.sbomify.com/CVE-2026-55220/index.md","name":"CVE-2026-55220","record":{"aliases":["GHSA-w23p-wrp7-ch38"],"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":"none","summary":"Attackers with write access to specific database columns can trigger unsafe deserialization in Pimcore, leading to arbitrary code execution or file writes.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Pimcore is an Open Source Data \u0026 Experience Management Platform. Prior to 11.5.19, 12.3.10, and 2026.1.6, Pimcore\\Model\\DataObject\\ClassDefinition\\Data\\Hotspotimage::getDataFromResource() in models/DataObject/ClassDefinition/Data/Hotspotimage.php passes the field __hotspots object-store column to Pimcore\\Tool\\Serialize::unserialize() without an allowed-classes restriction after JSON decoding fails. An attacker with a separate capability to write crafted PHP serialized bytes into that column can instantiate available classes and trigger magic methods when an affected DataObject is loaded, which can produce arbitrary file writes or code execution through bundled gadget chains. The related ImageGallery, Block, and Video callers use the same fallback pattern, but the identified June fix changes the Hotspotimage caller only. This issue is fixed for Hotspotimage 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":"none_known"},"has_fix":true,"headline":"Pimcore Hotspotimage getDataFromResource() unrestricted Serialize::unserialize over object-store column","id":"CVE-2026-55220","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":4,"n_references":5,"next":{"headline":"Boruta: OAuth credentials exposed in Boruta business logs","id":"CVE-2026-55221"},"packages":[{"ecosystem":"Packagist","fixed":["12.3.10"],"introduced":["0"],"last_affected":[],"package":"pimcore/pimcore","purl":null,"source":"GHSA-w23p-wrp7-ch38"},{"ecosystem":"Packagist","fixed":["12.3.10"],"introduced":["0"],"last_affected":[],"package":"pimcore/pimcore","purl":"pkg:composer/pimcore/pimcore","source":"GHSA-w23p-wrp7-ch38"},{"ecosystem":"Packagist","fixed":["2026.1.6"],"introduced":["2026.1.0"],"last_affected":[],"package":"pimcore/pimcore","purl":null,"source":"GHSA-w23p-wrp7-ch38"},{"ecosystem":"Packagist","fixed":["2026.1.6"],"introduced":["2026.1.0"],"last_affected":[],"package":"pimcore/pimcore","purl":"pkg:composer/pimcore/pimcore","source":"GHSA-w23p-wrp7-ch38"}],"prev":{"headline":"Paymenter: Race condition in payWithCredit() enables credit double-spend","id":"CVE-2026-55219"},"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-31","vendors":["pimcore"]},"summary":"Attackers with write access to specific database columns can trigger unsafe deserialization in Pimcore, leading to arbitrary code execution or file writes.","url":"https://insights.sbomify.com/CVE-2026-55220/"}
