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-2021-24126 in the wild and no public exploit code.\n\nAffected product: Unknown Envira Gallery Lite. 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-2021-24126/ (Markdown: https://insights.sbomify.com/CVE-2021-24126/index.md)","id":"CVE-2021-24126","markdown":"https://insights.sbomify.com/CVE-2021-24126/index.md","name":"CVE-2021-24126","record":{"aliases":["GHSA-2564-4rf9-wv93"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts via image metadata in Envira Gallery Lite, potentially leading to privilege escalation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"envira_gallery","vendor":"enviragallery"}],"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":"Unvalidated input and lack of output encoding in the Envira Gallery Lite WordPress plugin, versions before 1.8.3.3, did not properly sanitise the images metadata (namely title) before outputting them in the generated gallery, which could lead to privilege escalation.","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":"Envira Gallery Lite \u003c 1.8.3.3 - Authenticated Stored Cross-Site Scripting","id":"CVE-2021-24126","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"ThirstyAffiliates \u003c 3.9.3 - Authenticated Stored XSS","id":"CVE-2021-24127"},"packages":[],"prev":{"headline":"Contact Form Submissions \u003c 1.7.1 - Authenticated SQL Injection","id":"CVE-2021-24125"},"products":["Envira Gallery Lite"],"published":"2021-03-18","related":[{"cvss_score":6.1,"headline":"Envira Gallery Lite \u003c 1.8.4.7 - Reflected Cross-Site Scripting","id":"CVE-2022-2190","kev_date_added":null,"published":"2022-10-31"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2020-35581","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2020-35582","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2020-9334","kev_date_added":null,"published":"2020-02-25"},{"cvss_score":4.8,"headline":"Envira Gallery \u003c 1.8.15 - Author+ Stored XSS","id":"CVE-2024-3899","kev_date_added":null,"published":"2024-09-11"},{"cvss_score":4.3,"headline":"WordPress Envira Gallery Lite plugin \u003c= 1.8.14 - Broken Access Control vulnerability","id":"CVE-2024-43925","kev_date_added":null,"published":"2024-11-01"}],"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":"Authenticated attackers can inject malicious scripts via image metadata in Envira Gallery Lite, potentially leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2021-24126/"}
