Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4334 in the wild and no public exploit code.\n\nAffected product: 3uu Shariff Wrapper. 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-2026-4334/ (Markdown: https://insights.sbomify.com/CVE-2026-4334/index.md)","id":"CVE-2026-4334","markdown":"https://insights.sbomify.com/CVE-2026-4334/index.md","name":"CVE-2026-4334","record":{"aliases":["GHSA-xp36-f956-vp7p"],"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":"Authenticated contributors can inject arbitrary scripts via the headline parameter in the Shariff Wrapper plugin, leading to stored XSS.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/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 Shariff Wrapper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'headline' parameter in the [shariff] shortcode in all versions up to, and including, 4.6.20 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability occurs because the plugin uses a custom wp_kses implementation with permissive allowed HTML tags, and then performs a str_replace operation that injects HTML after sanitization, allowing event handlers to be introduced through the %total placeholder in the style attribute.","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":"Shariff Wrapper \u003c= 4.6.20 - Authenticated (Contributor+) Cross-Site Scripting","id":"CVE-2026-4334","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"ShortPixel Image Optimizer \u003c= 6.4.3 - Authenticated (Author+) Stored Cross-Site Scripting via Attachment Title","id":"CVE-2026-4335"},"packages":[],"prev":{"headline":"LearnPress \u003c= 4.3.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'skin' Shortcode Attribute","id":"CVE-2026-4333"},"products":["Shariff Wrapper"],"published":"2026-05-28","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":"2026-05-28","vendors":["3uu"]},"summary":"Authenticated contributors can inject arbitrary scripts via the headline parameter in the Shariff Wrapper plugin, leading to stored XSS.","url":"https://insights.sbomify.com/CVE-2026-4334/"}
