Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16942 exists.\n\nAffected product: Unknown WP Custom HTML Page. 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-2026-16942/ (Markdown: https://insights.sbomify.com/CVE-2026-16942/index.md)","id":"CVE-2026-16942","markdown":"https://insights.sbomify.com/CVE-2026-16942/index.md","name":"CVE-2026-16942","record":{"aliases":["GHSA-34jf-wc5v-9rcm"],"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":"low_privilege","summary":"Authors can inject JavaScript via custom HTML pages, leading to code execution and potential account takeover for visitors including administrators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The WP Custom HTML Page WordPress plugin through 0.6.2 does not sanitise HTML stored through one of its custom page handlers, nor restrict it to users allowed to post unfiltered HTML, allowing users with the Author role to store JavaScript that is served unescaped at a public URL and executes for any visitor, including administrators.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"WP Custom HTML Pages \u003c= 0.6.2 - Author+ Stored XSS","id":"CVE-2026-16942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-16943"},"packages":[],"prev":{"headline":"IBM i is Affected By An Incorrect Authorization Vulnerability []","id":"CVE-2026-16941"},"products":["WP Custom HTML Page"],"published":"2026-08-05","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Unknown"]},"summary":"Authors can inject JavaScript via custom HTML pages, leading to code execution and potential account takeover for visitors including administrators.","url":"https://insights.sbomify.com/CVE-2026-16942/"}
