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-2026-31867 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- craftcms/commerce (Packagist): affected from 4.0.0; fixed in 4.11.0\n- craftcms/commerce (Packagist): affected from 4.0.0; fixed in 4.11.0\n- craftcms/commerce (Packagist): affected from 5.0.0; fixed in 5.6.0\n- craftcms/commerce (Packagist): affected from 5.0.0; fixed in 5.6.0\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-2026-31867/ (Markdown: https://insights.sbomify.com/CVE-2026-31867/index.md)","id":"CVE-2026-31867","markdown":"https://insights.sbomify.com/CVE-2026-31867/index.md","name":"CVE-2026-31867","record":{"aliases":["GHSA-vff3-pqq8-4cpq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft Commerce plugin","requires_auth":"none","summary":"Attackers can hijack shopping carts and access PII by guessing cart IDs due to missing ownership validation in Craft Commerce.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"craft_commerce","vendor":"craftcms"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.11.0 and 5.6.0, An Insecure Direct Object Reference (IDOR) vulnerability exists in Craft Commerce’s cart functionality that allows users to hijack any shopping cart by knowing or guessing its 32-character number. The CartController accepts a user-supplied number parameter to load and modify shopping carts. No ownership validation is performed - the code only checks if the order exists and is incomplete, not whether the requester has authorization to access it. This vulnerability enables the takeover of shopping sessions and potential exposure of PII. This vulnerability is fixed in 4.11.0 and 5.6.0.","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":"Craft Commerce has a Potential IDOR in Commerce carts","id":"CVE-2026-31867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Parse Server has Stored XSS via file upload of HTML-renderable file types","id":"CVE-2026-31868"},"packages":[{"ecosystem":"Packagist","fixed":["4.11.0"],"introduced":["4.0.0"],"last_affected":[],"package":"craftcms/commerce","purl":null,"source":"GHSA-vff3-pqq8-4cpq"},{"ecosystem":"Packagist","fixed":["4.11.0"],"introduced":["4.0.0"],"last_affected":[],"package":"craftcms/commerce","purl":"pkg:composer/craftcms/commerce","source":"GHSA-vff3-pqq8-4cpq"},{"ecosystem":"Packagist","fixed":["5.6.0"],"introduced":["5.0.0"],"last_affected":[],"package":"craftcms/commerce","purl":null,"source":"GHSA-vff3-pqq8-4cpq"},{"ecosystem":"Packagist","fixed":["5.6.0"],"introduced":["5.0.0"],"last_affected":[],"package":"craftcms/commerce","purl":"pkg:composer/craftcms/commerce","source":"GHSA-vff3-pqq8-4cpq"}],"prev":{"headline":"Allocation of Resources Without Limits or Throttling in flagd","id":"CVE-2026-31866"},"products":["commerce"],"published":"2026-03-11","related":[{"cvss_score":8.7,"headline":"Craft Commerce has a SQL Injection in Commerce Purchasables Table Sorting","id":"CVE-2026-29172","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.7,"headline":"Craft Commerce has a SQL Injection in Commerce Inventory Table Sorting","id":"CVE-2026-29174","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.6,"headline":"Multiple Stored XSS in Commerce Inventory Page Leading to Session Hijacking","id":"CVE-2026-29175","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":6.2,"headline":"Craft Commerce has Stored DOM XSS in Order Status Name (Reflects in \"Recent Orders\" Dashboard Widget)","id":"CVE-2026-25482","kev_date_added":null,"published":"2026-02-03"},{"cvss_score":6.2,"headline":"Craft Commerce has Stored XSS via Order Status Message with potential database exfiltration","id":"CVE-2026-25483","kev_date_added":null,"published":"2026-02-03"},{"cvss_score":6.2,"headline":"Craft Commerce has Stored XSS in Shipping Categories (Name \u0026 Description) Fields Leading to Potential Privilege Escalation","id":"CVE-2026-25485","kev_date_added":null,"published":"2026-02-03"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-12","vendors":["craftcms"]},"summary":"Attackers can hijack shopping carts and access PII by guessing cart IDs due to missing ownership validation in Craft Commerce.","url":"https://insights.sbomify.com/CVE-2026-31867/"}
