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-2026-42643 in the wild and no public exploit code.\n\nAffected product: StellarWP Image Widget. 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-2026-42643/ (Markdown: https://insights.sbomify.com/CVE-2026-42643/index.md)","id":"CVE-2026-42643","markdown":"https://insights.sbomify.com/CVE-2026-42643/index.md","name":"CVE-2026-42643","record":{"aliases":["GHSA-jc7j-6r64-945c"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Stored XSS in Image Widget allows attackers to inject malicious scripts into web pages viewed by other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 StellarWP Image Widget image-widget allows Stored XSS.This issue affects Image Widget: from n/a through \u003c= 4.4.11.","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 Image Widget plugin \u003c= 4.4.11 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-42643","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 BetterDocs plugin \u003c= 4.3.10 - Sensitive Data Exposure vulnerability","id":"CVE-2026-42644"},"packages":[],"prev":{"headline":"WordPress GiveWP plugin \u003c= 4.14.5 - Broken Access Control vulnerability","id":"CVE-2026-42642"},"products":["Image Widget"],"published":"2026-04-29","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":"2026-05-12","vendors":["StellarWP"]},"summary":"Stored XSS in Image Widget allows attackers to inject malicious scripts into web pages viewed by other users.","url":"https://insights.sbomify.com/CVE-2026-42643/"}
