Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-51503 exists.\n\nAffected packages and fixed versions:\n- microweber/microweber (Packagist): affected from 2.0.0 up to 2.0.19; no fix listed\n- microweber/microweber (Packagist): affected from 2.0.0 up to 2.0.19; 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-2025-51503/ (Markdown: https://insights.sbomify.com/CVE-2025-51503/index.md)","id":"CVE-2025-51503","markdown":"https://insights.sbomify.com/CVE-2025-51503/index.md","name":"CVE-2025-51503","record":{"aliases":["GHSA-782f-gxj5-xvqc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Microweber CMS","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into user profile fields, leading to arbitrary JavaScript execution in admin browsers.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"microweber","vendor":"microweber"}],"cvss":{"score":7.6,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Stored Cross-Site Scripting (XSS) vulnerability in Microweber CMS 2.0 allows attackers to inject malicious scripts into user profile fields, leading to arbitrary JavaScript execution in admin browsers.","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":"Microweber Has Stored XSS Vulnerability in User Profile Fields","id":"CVE-2025-51503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"microweber:microweber","products":["microweber:microweber"],"type":"xss","year":"2025"},"n_packages":2,"n_references":3,"next":{"headline":"Microweber XSS Vulnerability in the homepage Endpoint","id":"CVE-2025-51504"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["2.0.0"],"last_affected":["2.0.19"],"package":"microweber/microweber","purl":null,"source":"GHSA-782f-gxj5-xvqc"},{"ecosystem":"Packagist","fixed":[],"introduced":["2.0.0"],"last_affected":["2.0.19"],"package":"microweber/microweber","purl":"pkg:composer/microweber/microweber","source":"GHSA-782f-gxj5-xvqc"}],"prev":{"headline":"Microweber has Reflected XSS Vulnerability in the layout Parameter","id":"CVE-2025-51502"},"products":["n/a"],"published":"2025-07-31","related":[{"cvss_score":9.8,"headline":"Cross-site Scripting (XSS) - Stored in microweber/microweber","id":"CVE-2022-0558","kev_date_added":null,"published":"2022-02-10"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2020-23138","kev_date_added":null,"published":"2020-11-09"},{"cvss_score":9.4,"headline":"Business Logic Errors in microweber/microweber","id":"CVE-2022-0688","kev_date_added":null,"published":"2022-02-20"},{"cvss_score":9.4,"headline":"Generation of Error Message Containing Sensitive Information in microweber/microweber","id":"CVE-2022-0660","kev_date_added":null,"published":"2022-02-18"},{"cvss_score":9.1,"headline":"Integer Overflow or Wraparound in microweber/microweber","id":"CVE-2022-0913","kev_date_added":null,"published":"2022-03-11"},{"cvss_score":9.1,"headline":"Insecure Storage of Sensitive Information in microweber/microweber","id":"CVE-2022-0724","kev_date_added":null,"published":"2022-02-23"},{"cvss_score":8.8,"headline":"Microweber file upload vulnerability","id":"CVE-2023-49052","kev_date_added":null,"published":"2023-11-30"}],"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":"2025-07-31","vendors":["n/a"]},"summary":"Attackers can inject malicious scripts into user profile fields, leading to arbitrary JavaScript execution in admin browsers.","url":"https://insights.sbomify.com/CVE-2025-51503/"}
