An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-16559 in the wild and no public exploit code.\n\nAffected product: Unknown YMC Filter. 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-2026-16559/ (Markdown: https://insights.sbomify.com/CVE-2026-16559/index.md)","id":"CVE-2026-16559","markdown":"https://insights.sbomify.com/CVE-2026-16559/index.md","name":"CVE-2026-16559","record":{"aliases":["GHSA-qgw2-v7vq-9g5r"],"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":"high_privilege","summary":"Authors can upload malicious SVG files containing JavaScript, leading to stored XSS execution in the site's origin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The YMC Filter WordPress plugin before 3.12.9 does not sanitize SVG files uploaded through one of its icon upload features and permits their upload by low-privileged users, allowing users with the Author role and above to upload a file containing JavaScript that executes in the site's origin when the file is viewed.","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":"YMC Filter \u003c 3.12.9 - Author+ Stored XSS via SVG Icon Upload","id":"CVE-2026-16559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"389-ds-base: 389-ds-base: heap-buffer-overflow in rdn_av_swap on quoted multivalued rdn","id":"CVE-2026-16560"},"packages":[],"prev":{"headline":"YMC Filter \u003c 3.12.8 - Contributor+ Stored XSS via Layout Builder Schema","id":"CVE-2026-16558"},"products":["YMC Filter"],"published":"2026-08-08","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":"total"},"state":"PUBLISHED","updated":"2026-08-11","vendors":["Unknown"]},"summary":"Authors can upload malicious SVG files containing JavaScript, leading to stored XSS execution in the site's origin.","url":"https://insights.sbomify.com/CVE-2026-16559/"}
