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-2026-84829 in the wild and no public exploit code.\n\nAffected product: Unknown Optimole. 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-2026-84829/ (Markdown: https://insights.sbomify.com/CVE-2026-84829/index.md)","id":"CVE-2026-84829","markdown":"https://insights.sbomify.com/CVE-2026-84829/index.md","name":"CVE-2026-84829","record":{"aliases":["GHSA-mwqj-x4rq-9232"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject arbitrary scripts into pages via the srcset descriptor parameter, affecting all visitors of sites using the Optimole plugin.","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 Optimole  WordPress plugin before 4.2.12 does not properly escape a user supplied value before using it to build an image tag attribute, allowing unauthenticated users to inject arbitrary attributes into pages served to every visitor, which leads to Stored Cross-Site Scripting.","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":"Optimole \u003c 4.2.12 - Unauthenticated Stored XSS via Srcset Descriptor Parameter","id":"CVE-2026-84829","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"OS command injection in privileged configuration handling","id":"CVE-2026-84830"},"packages":[],"prev":{"headline":"Pcs: pcs: non-root haclient users can read arbitrary files via pcs host auth --token","id":"CVE-2026-84828"},"products":["Optimole"],"published":"2026-09-16","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":"2026-09-17","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject arbitrary scripts into pages via the srcset descriptor parameter, affecting all visitors of sites using the Optimole plugin.","url":"https://insights.sbomify.com/CVE-2026-84829/"}
