An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-88903 in the wild and no public exploit code.\n\nAffected product: Unknown Topcontent. 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-2026-88903/ (Markdown: https://insights.sbomify.com/CVE-2026-88903/index.md)","id":"CVE-2026-88903","markdown":"https://insights.sbomify.com/CVE-2026-88903/index.md","name":"CVE-2026-88903","record":{"aliases":["GHSA-vrpv-vc9c-j35f"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious JavaScript into posts via webhook if the plugin's API key is unconfigured, leading to stored XSS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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 Topcontent WordPress plugin through 1.2.1 does not properly authorise one of its request handlers and disables HTML sanitisation before storing the submitted content, allowing unauthenticated attackers to publish arbitrary posts containing malicious JavaScript on any site where its API key has never been configured.","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":"Topcontent \u003c= 1.2.1 - Unauthenticated Stored XSS via Content Webhook","id":"CVE-2026-88903","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"PuppyFW \u003c= 0.4.4 - Subscriber+ Arbitrary Blog Options Update and Deletion Leading to Privilege Escalation","id":"CVE-2026-88904"},"packages":[],"prev":{"headline":"Apache Camel: Camel-Smooks XML External Entity Processing, external entities resolved by default","id":"CVE-2026-88901"},"products":["Topcontent"],"published":"2026-10-11","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":"2026-10-11","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious JavaScript into posts via webhook if the plugin's API key is unconfigured, leading to stored XSS.","url":"https://insights.sbomify.com/CVE-2026-88903/"}
