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-2021-24903 in the wild and no public exploit code.\n\nAffected product: Unknown Album and Image Gallery with Lightbox – Flagallery Photo Portfolio. 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-2021-24903/ (Markdown: https://insights.sbomify.com/CVE-2021-24903/index.md)","id":"CVE-2021-24903","markdown":"https://insights.sbomify.com/CVE-2021-24903/index.md","name":"CVE-2021-24903","record":{"aliases":["GHSA-p9r5-6jx9-h5wp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"High-privilege users can inject malicious scripts into gallery settings, bypassing security filters to execute code in other users' browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"grand_flagallery","vendor":"codeasily"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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 GRAND FlaGallery WordPress plugin through 6.1.2 does not sanitise and escape some of its gallery settings, which could allow high privilege users to perform Cross-Site scripting attacks even when the unfiltered_html capability is disallowed.","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":"GRAND FlaGallery \u003c= 6.1.2 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24903","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Mortgage Calculators WP \u003c 1.56 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24904"},"packages":[],"prev":{"headline":"Typebot \u003c 1.4.3 - Admin+ Stored Cross Site Scripting","id":"CVE-2021-24902"},"products":["Album and Image Gallery with Lightbox – Flagallery Photo Portfolio"],"published":"2022-02-28","related":[{"cvss_score":5.3,"headline":"Information disclosure in n/a","id":"CVE-2014-8491","kev_date_added":null,"published":"2017-10-18"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2011-4624","kev_date_added":null,"published":"2014-10-01"}],"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":"High-privilege users can inject malicious scripts into gallery settings, bypassing security filters to execute code in other users' browsers.","url":"https://insights.sbomify.com/CVE-2021-24903/"}
