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-2023-0559 exists.\n\nAffected product: Unknown GS Portfolio for Envato. 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-2023-0559/ (Markdown: https://insights.sbomify.com/CVE-2023-0559/index.md)","id":"CVE-2023-0559","markdown":"https://insights.sbomify.com/CVE-2023-0559/index.md","name":"CVE-2023-0559","record":{"aliases":["GHSA-w3v6-4gf2-mrx7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Contributors can inject malicious scripts via shortcode attributes in the GS Portfolio for Envato plugin, leading to stored XSS attacks.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"gs_portfolio_for_envato","vendor":"gsplugins"}],"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":[],"description":"The GS Portfolio for Envato WordPress plugin before 1.4.0 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embedded, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"GS Portfolio for Envato \u003c 1.4.0 - Contributor+ Stored XSS","id":"CVE-2023-0559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"SourceCodester Online Tours \u0026 Travels Management System practice_pdf.php sql injection","id":"CVE-2023-0560"},"packages":[],"prev":{"headline":"ContentStudio \u003c= 1.2.5 - Authorization Bypass","id":"CVE-2023-0558"},"products":["GS Portfolio for Envato"],"published":"2023-02-21","related":[],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-14","vendors":["Unknown"]},"summary":"Contributors can inject malicious scripts via shortcode attributes in the GS Portfolio for Envato plugin, leading to stored XSS attacks.","url":"https://insights.sbomify.com/CVE-2023-0559/"}
