An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-66121 in the wild and no public exploit code.\n\nAffected product: SiteGround Security. 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-2025-66121/ (Markdown: https://insights.sbomify.com/CVE-2025-66121/index.md)","id":"CVE-2025-66121","markdown":"https://insights.sbomify.com/CVE-2025-66121/index.md","name":"CVE-2025-66121","record":{"aliases":["GHSA-j9wm-m2fc-3vmp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress security plugin","requires_auth":"none","summary":"Attackers can bypass access controls in the SiteGround Security plugin for WordPress, potentially accessing restricted functionality.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing Authorization vulnerability in SiteGround SiteGround Security sg-security allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects SiteGround Security: from n/a through \u003c= 1.5.8.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"WordPress SiteGround Security plugin \u003c= 1.5.8 - Broken Access Control vulnerability","id":"CVE-2025-66121","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Stylish Price List plugin \u003c= 7.2.2 - Broken Access Control vulnerability","id":"CVE-2025-66122"},"packages":[],"prev":{"headline":"WordPress CatFolders plugin \u003c= 2.5.3 - Broken Access Control vulnerability","id":"CVE-2025-66120"},"products":["SiteGround Security"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["SiteGround"]},"summary":"Attackers can bypass access controls in the SiteGround Security plugin for WordPress, potentially accessing restricted functionality.","url":"https://insights.sbomify.com/CVE-2025-66121/"}
