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-2023-4655 exists.\n\nAffected product: instantsoft/icms2. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-4655/ (Markdown: https://insights.sbomify.com/CVE-2023-4655/index.md)","id":"CVE-2023-4655","markdown":"https://insights.sbomify.com/CVE-2023-4655/index.md","name":"CVE-2023-4655","record":{"aliases":["GHSA-5x3r-fvpc-645c"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"InstantCMS","requires_auth":"low_privilege","summary":"Reflected Cross-Site Scripting in InstantCMS allows attackers to execute arbitrary scripts in victim browsers, potentially leading to session hijacking or data theft.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"instantcms","vendor":"instantcms"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site Scripting (XSS) - Reflected in GitHub repository instantsoft/icms2 prior to 2.16.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site Scripting (XSS) - Reflected in instantsoft/icms2","id":"CVE-2023-4655","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-4656"},"packages":[],"prev":{"headline":"Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in instantsoft/icms2","id":"CVE-2023-4654"},"products":["instantsoft/icms2"],"published":"2023-08-31","related":[{"cvss_score":9.8,"headline":"SQL Injection in instantsoft/icms2","id":"CVE-2023-4188","kev_date_added":null,"published":"2023-08-05"},{"cvss_score":9.3,"headline":"InstantCMS \u003c= 1.6 Remote PHP Code Execution","id":"CVE-2013-10051","kev_date_added":null,"published":"2025-08-01"},{"cvss_score":8.8,"headline":"External Control of System or Configuration Setting in instantsoft/icms2","id":"CVE-2023-4704","kev_date_added":null,"published":"2023-09-01"},{"cvss_score":7.1,"headline":"InstantCMS has Multiple CSRF Vulnerabilities","id":"CVE-2026-28281","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":6.8,"headline":"Cross-site Scripting (XSS) - Stored in instantsoft/icms2","id":"CVE-2023-4652","kev_date_added":null,"published":"2023-08-31"},{"cvss_score":6.7,"headline":"SQL injection in index_chart_data action","id":"CVE-2024-31212","kev_date_added":null,"published":"2024-04-04"},{"cvss_score":6.4,"headline":"Server-Side Request Forgery (SSRF) in instantsoft/icms2","id":"CVE-2023-4651","kev_date_added":null,"published":"2023-08-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-10-01","vendors":["instantsoft"]},"summary":"Reflected Cross-Site Scripting in InstantCMS allows attackers to execute arbitrary scripts in victim browsers, potentially leading to session hijacking or data theft.","url":"https://insights.sbomify.com/CVE-2023-4655/"}
