An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-31823 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sylius/sylius (Packagist): affected from 2.0.0; fixed in 2.0.16\n- sylius/sylius (Packagist): affected from 2.0.0; fixed in 2.0.16\n- sylius/sylius (Packagist): affected from 2.1.0; fixed in 2.1.12\n- sylius/sylius (Packagist): affected from 2.1.0; fixed in 2.1.12\n- sylius/sylius (Packagist): affected from 2.2.0; fixed in 2.2.3\n- sylius/sylius (Packagist): affected from 2.2.0; fixed in 2.2.3\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-2026-31823/ (Markdown: https://insights.sbomify.com/CVE-2026-31823/index.md)","id":"CVE-2026-31823","markdown":"https://insights.sbomify.com/CVE-2026-31823/index.md","name":"CVE-2026-31823","record":{"aliases":["GHSA-mx4q-xxc9-pf5q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Sylius eCommerce Framework","requires_auth":"high_privilege","summary":"Authenticated attackers can inject persistent JavaScript via unsanitized entity names in Sylius, affecting both storefront and admin panels.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sylius","vendor":"sylius"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Sylius is an Open Source eCommerce Framework on Symfony. An authenticated stored cross-site scripting (XSS) vulnerability exists in multiple places across the shop frontend and admin panel due to unsanitized entity names being rendered as raw HTML. Shop breadcrumbs (shared/breadcrumbs.html.twig): The breadcrumbs macro uses the Twig |raw filter on label values. Since taxon names, product names, and ancestor names flow directly into these labels, a malicious taxon name like \u003cimg src=x onerror=alert('XSS')\u003e is rendered and executed as JavaScript on the storefront. Admin product taxon picker (ProductTaxonTreeController.js): The rowRenderer method interpolates ${name} directly into a template literal building HTML, allowing script injection through taxon names in the admin panel. Admin autocomplete fields (Tom Select): Dropdown items and options render entity names as raw HTML without escaping, allowing XSS through any autocomplete field displaying entity names. An authenticated administrator can inject arbitrary HTML or JavaScript via entity names (e.g. taxon name) that is persistently rendered for all users. The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 and above.","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":"Sylius has Authenticated Stored XSS","id":"CVE-2026-31823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":6,"n_references":1,"next":{"headline":"Sylius has a Promotion Usage Limit Bypass via Race Condition","id":"CVE-2026-31824"},"packages":[{"ecosystem":"Packagist","fixed":["2.0.16"],"introduced":["2.0.0"],"last_affected":[],"package":"sylius/sylius","purl":null,"source":"GHSA-mx4q-xxc9-pf5q"},{"ecosystem":"Packagist","fixed":["2.0.16"],"introduced":["2.0.0"],"last_affected":[],"package":"sylius/sylius","purl":"pkg:composer/sylius/sylius","source":"GHSA-mx4q-xxc9-pf5q"},{"ecosystem":"Packagist","fixed":["2.1.12"],"introduced":["2.1.0"],"last_affected":[],"package":"sylius/sylius","purl":null,"source":"GHSA-mx4q-xxc9-pf5q"},{"ecosystem":"Packagist","fixed":["2.1.12"],"introduced":["2.1.0"],"last_affected":[],"package":"sylius/sylius","purl":"pkg:composer/sylius/sylius","source":"GHSA-mx4q-xxc9-pf5q"},{"ecosystem":"Packagist","fixed":["2.2.3"],"introduced":["2.2.0"],"last_affected":[],"package":"sylius/sylius","purl":null,"source":"GHSA-mx4q-xxc9-pf5q"},{"ecosystem":"Packagist","fixed":["2.2.3"],"introduced":["2.2.0"],"last_affected":[],"package":"sylius/sylius","purl":"pkg:composer/sylius/sylius","source":"GHSA-mx4q-xxc9-pf5q"}],"prev":{"headline":"Sylius has a XSS vulnerability in checkout login form","id":"CVE-2026-31822"},"products":["Sylius"],"published":"2026-03-10","related":[{"cvss_score":8.2,"headline":"Sylius has a Promotion Usage Limit Bypass via Race Condition","id":"CVE-2026-31824","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-57610","kev_date_added":null,"published":"2025-02-06"},{"cvss_score":7.1,"headline":"Sylius affected by IDOR in Cart and Checkout LiveComponents","id":"CVE-2026-31820","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":7.1,"headline":"Insufficient Session Expiration in Sylius","id":"CVE-2022-24743","kev_date_added":null,"published":"2022-03-14"},{"cvss_score":6.9,"headline":"Sylius has an Open Redirect via Referer Header","id":"CVE-2026-31819","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":6.9,"headline":"Sylius is Missing Authorization in API v2 Add Item Endpoint","id":"CVE-2026-31821","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":6.4,"headline":"Sylius has potential Cross Site Scripting vulnerability via the \"Province\" field in the Checkout and Address Book","id":"CVE-2024-29376","kev_date_added":null,"published":"2024-04-22"}],"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":"2026-03-11","vendors":["Sylius"]},"summary":"Authenticated attackers can inject persistent JavaScript via unsanitized entity names in Sylius, affecting both storefront and admin panels.","url":"https://insights.sbomify.com/CVE-2026-31823/"}
