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-2022-39357 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- wintercms/winter (Packagist): affected from 1.1.8; fixed in 1.1.10\n- wintercms/winter (Packagist): affected from 1.1.8; fixed in 1.1.10\n- wintercms/winter (Packagist): affected from 1.2.0; fixed in 1.2.1\n- wintercms/winter (Packagist): affected from 1.2.0; fixed in 1.2.1\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-2022-39357/ (Markdown: https://insights.sbomify.com/CVE-2022-39357/index.md)","id":"CVE-2022-39357","markdown":"https://insights.sbomify.com/CVE-2022-39357/index.md","name":"CVE-2022-39357","record":{"aliases":["GHSA-3fh5-q6fg-w28q"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Winter CMS","requires_auth":"none","summary":"Prototype pollution in Winter CMS Snowboard framework allows attackers to manipulate objects, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"winter","vendor":"wintercms"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Winter is a free, open-source content management system based on the Laravel PHP framework. The Snowboard framework in versions 1.1.8, 1.1.9, and 1.2.0 is vulnerable to prototype pollution in the main Snowboard class as well as its plugin loader. The 1.0 branch of Winter is not affected, as it does not contain the Snowboard framework. This issue has been patched in v1.1.10 and v1.2.1. As a workaround, one may avoid this issue by following some common security practices for JavaScript, including implementing a content security policy and auditing scripts.","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":"Winter vulnerable to Prototype Pollution in Snowboard framework","id":"CVE-2022-39357","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"other","year":"2022"},"n_packages":4,"n_references":5,"next":{"headline":"Metabase vulnerable to circumvention of Locked parameter in Signed Embedding","id":"CVE-2022-39358"},"packages":[{"ecosystem":"Packagist","fixed":["1.1.10"],"introduced":["1.1.8"],"last_affected":[],"package":"wintercms/winter","purl":null,"source":"GHSA-3fh5-q6fg-w28q"},{"ecosystem":"Packagist","fixed":["1.1.10"],"introduced":["1.1.8"],"last_affected":[],"package":"wintercms/winter","purl":"pkg:composer/wintercms/winter","source":"GHSA-3fh5-q6fg-w28q"},{"ecosystem":"Packagist","fixed":["1.2.1"],"introduced":["1.2.0"],"last_affected":[],"package":"wintercms/winter","purl":null,"source":"GHSA-3fh5-q6fg-w28q"},{"ecosystem":"Packagist","fixed":["1.2.1"],"introduced":["1.2.0"],"last_affected":[],"package":"wintercms/winter","purl":"pkg:composer/wintercms/winter","source":"GHSA-3fh5-q6fg-w28q"}],"prev":{"headline":"Discourse user account takeover via email and invite link","id":"CVE-2022-39356"},"products":["winter"],"published":"2022-10-26","related":[{"cvss_score":10,"headline":"Winter: Privilege escalation by authenticated backend users","id":"CVE-2026-27591","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":8.5,"headline":"Winter CMS Modules allows a sandbox bypass in Twig templates leading to data modification and deletion","id":"CVE-2024-54149","kev_date_added":null,"published":"2024-12-09"},{"cvss_score":7.2,"headline":"Winter CMS Server-Side Template Injection (SSTI) vulnerability","id":"CVE-2024-29686","kev_date_added":null,"published":"2024-03-29"},{"cvss_score":3.3,"headline":"Winter CMS Local File Inclusion through Server Side Template Injection","id":"CVE-2023-52085","kev_date_added":null,"published":"2023-12-29"},{"cvss_score":2,"headline":"Stored XSS through privileged upload of Media Manager file followed by renaming","id":"CVE-2023-52083","kev_date_added":null,"published":"2023-12-28"},{"cvss_score":2,"headline":"Winter CMS Stored XSS through Backend ColorPicker FormWidget","id":"CVE-2023-52084","kev_date_added":null,"published":"2023-12-28"}],"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":"total"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["wintercms"]},"summary":"Prototype pollution in Winter CMS Snowboard framework allows attackers to manipulate objects, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2022-39357/"}
