Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-27403 in the wild and no public exploit code.\n\nAffected product: NerdPress Hubbub Lite. 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-2026-27403/ (Markdown: https://insights.sbomify.com/CVE-2026-27403/index.md)","id":"CVE-2026-27403","markdown":"https://insights.sbomify.com/CVE-2026-27403/index.md","name":"CVE-2026-27403","record":{"aliases":["GHSA-583w-xvr4-75jr"],"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":"Stored XSS in Hubbub Lite allows attackers to inject malicious scripts, 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":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in NerdPress Hubbub Lite allows Stored XSS.\n\nThis issue affects Hubbub Lite: from n/a through 1.36.3.","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 Hubbub Lite plugin \u003c= 1.36.3 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-27403","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 LMS theme \u003c= 9.7 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-27404"},"packages":[],"prev":{"headline":"WordPress Kids Life | Children School WordPress theme \u003c= 5.2 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-27402"},"products":["Hubbub Lite"],"published":"2026-07-23","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":"2026-07-23","vendors":["NerdPress"]},"summary":"Stored XSS in Hubbub Lite allows attackers to inject malicious scripts, potentially compromising user sessions and site integrity.","url":"https://insights.sbomify.com/CVE-2026-27403/"}
