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-2026-74921 in the wild and no public exploit code.\n\nAffected product: Unknown Document Gallery. 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-2026-74921/ (Markdown: https://insights.sbomify.com/CVE-2026-74921/index.md)","id":"CVE-2026-74921","markdown":"https://insights.sbomify.com/CVE-2026-74921/index.md","name":"CVE-2026-74921","record":{"aliases":["GHSA-5xmq-vg89-7x44"],"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":"Contributors can inject malicious scripts via gallery shortcode attributes, leading to code execution when viewed by higher-privileged users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","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 Document Gallery WordPress plugin through 5.1.1 does not sanitise or escape several gallery shortcode attributes before embedding them in a single-quoted HTML attribute in the rendered gallery markup, allowing users with the Contributor role and above to inject arbitrary event handlers that execute when a higher privileged user views the content.","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":"Document Gallery 4.0 - 5.1.1 - Contributor+ Stored XSS via Gallery Shortcode Attributes","id":"CVE-2026-74921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Document Gallery 4.1 - 5.1.1 - Unauthenticated Document Thumbnail Replacement via Thumber Webhook Signature Bypass","id":"CVE-2026-74922"},"packages":[],"prev":{"headline":"Document Gallery \u003c= 5.1.1 - Reflected XSS via data-shortcode Attribute","id":"CVE-2026-74920"},"products":["Document Gallery"],"published":"2026-10-19","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":"2026-10-19","vendors":["Unknown"]},"summary":"Contributors can inject malicious scripts via gallery shortcode attributes, leading to code execution when viewed by higher-privileged users.","url":"https://insights.sbomify.com/CVE-2026-74921/"}
