Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-31350 exists.\n\nAffected packages and fixed versions:\n- feehi/cms (Packagist): affected all versions; no fix listed\n- feehi/cms (Packagist): affected all versions; no fix listed\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-2026-31350/ (Markdown: https://insights.sbomify.com/CVE-2026-31350/index.md)","id":"CVE-2026-31350","markdown":"https://insights.sbomify.com/CVE-2026-31350/index.md","name":"CVE-2026-31350","record":{"aliases":["GHSA-cgxr-v74v-g9mm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Feehi CMS","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary scripts via stored XSS in the Page Sign parameter of Feehi CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"feehi_cms","vendor":"feehi"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"An authenticated stored cross-site scripting (XSS) vulnerability in Feehi CMS v2.1.1 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Page Sign parameter.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Feehi CMS has an authenticated stored cross-site scripting (XSS) vulnerability via the Page Sign parameter","id":"CVE-2026-31350","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Feehi CMS has an authenticated stored cross-site scripting (XSS) vulnerability via the creation/editing module","id":"CVE-2026-31351"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":[],"last_affected":[],"package":"feehi/cms","purl":null,"source":"GHSA-cgxr-v74v-g9mm"},{"ecosystem":"Packagist","fixed":[],"introduced":[],"last_affected":[],"package":"feehi/cms","purl":"pkg:composer/feehi/cms","source":"GHSA-cgxr-v74v-g9mm"}],"prev":{"headline":"Craftql vulnerable to Server-Side Request Forgery","id":"CVE-2026-31317"},"products":["n/a"],"published":"2026-04-06","related":[{"cvss_score":9.1,"headline":"Server-Side Request Forgery in Feehi CMS","id":"CVE-2021-30108","kev_date_added":null,"published":"2021-05-24"},{"cvss_score":8.8,"headline":"Feehi CMS arbitrary code execution via crafted PHP file","id":"CVE-2022-34971","kev_date_added":null,"published":"2022-07-27"},{"cvss_score":7.2,"headline":"Feehi CMS arbitrary file upload vulnerability","id":"CVE-2020-22643","kev_date_added":null,"published":"2021-01-21"},{"cvss_score":6.1,"headline":"Feehi CMS host header injection vulnerability","id":"CVE-2022-38796","kev_date_added":null,"published":"2022-09-14"},{"cvss_score":6.1,"headline":"Feehi CMS vulnerable to Cross-site Scripting in Username Field","id":"CVE-2020-21146","kev_date_added":null,"published":"2021-01-21"},{"cvss_score":5.4,"headline":"Feehi CMS has an authenticated stored cross-site scripting (XSS) vulnerability via the creation/editing module","id":"CVE-2026-31313","kev_date_added":null,"published":"2026-04-06"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-09","vendors":["n/a"]},"summary":"Authenticated attackers can execute arbitrary scripts via stored XSS in the Page Sign parameter of Feehi CMS.","url":"https://insights.sbomify.com/CVE-2026-31350/"}
