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-2026-66705 in the wild and no public exploit code.\n\nAffected product: Facebook for WordPress. 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-2026-66705/ (Markdown: https://insights.sbomify.com/CVE-2026-66705/index.md)","id":"CVE-2026-66705","markdown":"https://insights.sbomify.com/CVE-2026-66705/index.md","name":"CVE-2026-66705","record":{"aliases":["GHSA-w2c9-5gcq-r387"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts via the Facebook for WordPress plugin, potentially compromising user sessions and 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 Facebook for WordPress \u003c= 5.2.1 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 Facebook for WordPress plugin \u003c= 5.2.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66705","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 Subscribe to Comments plugin \u003c= 2.3.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66706"},"packages":[],"prev":{"headline":"WordPress Gutenverse Companion plugin \u003c= 2.5.1 - Server Side Request Forgery (SSRF) vulnerability","id":"CVE-2026-66704"},"products":["Facebook for WordPress"],"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":"2026-08-06","vendors":["Facebook"]},"summary":"Unauthenticated attackers can inject malicious scripts via the Facebook for WordPress plugin, potentially compromising user sessions and site integrity.","url":"https://insights.sbomify.com/CVE-2026-66705/"}
