It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-103831 in the wild and no public exploit code.\n\nAffected product: TrueLayer Magento 2 Plugin. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-103831/ (Markdown: https://insights.sbomify.com/CVE-2026-103831/index.md)","id":"CVE-2026-103831","markdown":"https://insights.sbomify.com/CVE-2026-103831/index.md","name":"CVE-2026-103831","record":{"aliases":["GHSA-x69j-rqv7-gx25"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Magento 2 plugin","requires_auth":"none","summary":"An attacker with cache write access can inject malicious PHP objects into the TrueLayer Magento 2 plugin cache, leading to arbitrary code execution.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/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":"CVE-2026-103831: Insecure deserialization vulnerability in the Psr16CacheAdapter component of the TrueLayer Magento 2 Plugin, due to the use of PHP's native unserialize() function without restrictions on the classes allowed when retrieving data stored in the cache. An attacker who already has the ability to write manipulated data to the cache backend used by Magento—such as Redis or Memcached—could inject specially crafted PHP objects and trigger their deserialization, potentially leading to arbitrary code execution via gadget strings available in the application environment. Exploitation therefore requires a prerequisite condition that allows writing to the cache infrastructure, either through access to the local file system or to a cache infrastructure accessible from the Magento environment.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Insecure deserialization in the TrueLayer Magento 2 plugin","id":"CVE-2026-103831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Substance3D - Stager | Out-of-bounds Write (CWE-787)","id":"CVE-2026-103832"},"packages":[],"prev":{"headline":"Substance3D - Stager | Stack-based Buffer Overflow (CWE-121)","id":"CVE-2026-103830"},"products":["TrueLayer Magento 2 Plugin"],"published":"2026-10-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["TrueLayer"]},"summary":"An attacker with cache write access can inject malicious PHP objects into the TrueLayer Magento 2 plugin cache, leading to arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2026-103831/"}
