An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-36888 exists.\n\nAffected product: Oxilab Image Hover Effects Ultimate (WordPress plugin). 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-2021-36888/ (Markdown: https://insights.sbomify.com/CVE-2021-36888/index.md)","id":"CVE-2021-36888","markdown":"https://insights.sbomify.com/CVE-2021-36888/index.md","name":"CVE-2021-36888","record":{"aliases":["GHSA-8fjw-gv37-439q"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can arbitrarily update plugin options, leading to full website compromise and potential code execution.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"image_hover_effects","vendor":"blocksera"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Unauthenticated Arbitrary Options Update vulnerability leading to full website compromise discovered in Image Hover Effects Ultimate (versions \u003c= 9.6.1) WordPress plugin.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-36888.yaml","stars":null,"title":"WordPress Image Hover Ultimate - Unauthenticated Settings Update"}],"tier":"weaponised"},"has_fix":null,"headline":"Missing authorization in Image Hover Effects Ultimate (WordPress plugin)","id":"CVE-2021-36888","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in tarteaucitron.js – Cookies legislation \u0026 GDPR (WordPress plugin)","id":"CVE-2021-36889"},"packages":[],"prev":{"headline":"Cross-site request forgery in tarteaucitron.js – Cookies legislation \u0026 GDPR (WordPress plugin)","id":"CVE-2021-36887"},"products":["Image Hover Effects Ultimate (WordPress plugin)"],"published":"2021-12-15","related":[{"cvss_score":5.4,"headline":"Image Hover Effects - Elementor Addon \u003c 1.3.4 - Contributor+ Stored XSS","id":"CVE-2021-24264","kev_date_added":null,"published":"2021-05-05"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Oxilab"]},"summary":"Unauthenticated attackers can arbitrarily update plugin options, leading to full website compromise and potential code execution.","url":"https://insights.sbomify.com/CVE-2021-36888/"}
