Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-24439 in the wild and no public exploit code.\n\nAffected product: Unknown Browser Screenshots. 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-2021-24439/ (Markdown: https://insights.sbomify.com/CVE-2021-24439/index.md)","id":"CVE-2021-24439","markdown":"https://insights.sbomify.com/CVE-2021-24439/index.md","name":"CVE-2021-24439","record":{"aliases":["GHSA-7xfg-7frc-9fj7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Contributor-level users can inject malicious scripts via the image_class parameter in the Browser Screenshots plugin, potentially compromising other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"browser_screenshots","vendor":"prothemedesign"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Browser Screenshots WordPress plugin before 1.7.6 allowed authenticated users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks as the image_class parameter of the browser-shot shortcode was not escaped.","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":"Browser Screenshots \u003c 1.7.6 - Contributor+ Stored XSS","id":"CVE-2021-24439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Sign-up Sheets \u003c 1.0.14 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24440"},"packages":[],"prev":{"headline":"ShareThis Dashboard for Google Analytics \u003c 2.5.2 - Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24438"},"products":["Browser Screenshots"],"published":"2021-07-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Contributor-level users can inject malicious scripts via the image_class parameter in the Browser Screenshots plugin, potentially compromising other users.","url":"https://insights.sbomify.com/CVE-2021-24439/"}
