An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-66664 in the wild and no public exploit code.\n\nAffected product: SEO Plugin by Squirrly SEO. 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-2026-66664/ (Markdown: https://insights.sbomify.com/CVE-2026-66664/index.md)","id":"CVE-2026-66664","markdown":"https://insights.sbomify.com/CVE-2026-66664/index.md","name":"CVE-2026-66664","record":{"aliases":["GHSA-8x3x-hpv5-fj9r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress SEO plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts into the Squirrly SEO plugin, potentially compromising user sessions or site integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Unauthenticated Cross Site Scripting (XSS) in SEO Plugin by Squirrly SEO \u003c= 14.2.0 versions.","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 SEO plugin by Squirrly SEO plugin \u003c= 14.2.0 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66664","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Type Hub plugin \u003c= 2.0.6 - Arbitrary File Upload vulnerability","id":"CVE-2026-66665"},"packages":[],"prev":{"headline":"WordPress WP Data Access plugin \u003c= 5.5.79 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66663"},"products":["SEO Plugin by Squirrly SEO"],"published":"2026-08-06","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-08","vendors":["SEO Squirrly"]},"summary":"Unauthenticated attackers can inject malicious scripts into the Squirrly SEO plugin, potentially compromising user sessions or site integrity.","url":"https://insights.sbomify.com/CVE-2026-66664/"}
